Endurance Workout Training Videos and Tips

Endurance Workouts to Increase Your Energy and Stamina

Do you participate in an endurance sport or just want to improve your staying power? By adding high-intensity interval training, such as endurance workouts, to your routine, you can increase stamina, build muscle and burn fat. As you use all of your body's major muscles simultaneously, you boost your metabolism, which fuels weight loss. To reach your optimal level of performance, you need to make sure to maintain proper hydration, keep up your protein intake, improve your warm ups, increase strength training and get the right supplementation.

We want to see you go the distance, so we explored all of the incredible information out there to find some great ways to help you improve your aerobic and anaerobic endurance. While aerobic exercises improve your body's oxygen consumption and enlist slow-twitch muscles to be active for sustained periods of time, anaerobic exercises do not require oxygen to generate force and use fast-twitch muscles for short periods of time. Ideally every athlete wants a good balance of aerobic and anaerobic endurance. To give you the motivation you need to go faster and farther than ever before, we put together a few videos along with a Pinterest board dedicated to endurance workouts

Do HGH Releasers Really Work for Bodybuilders and Athletes?

A Candid Conversation About HGH Releasers and Other Natural Bodybuilding Supplements

By Dan Smith of HGH.com

Growth hormones have always been a hot – and often controversial – topic in the bodybuilding and sports worlds. As the public voice of HGH.com and Purity Select, I’ve frequently addressed the benefits of HGH releasers and bodybuilding supplements through our blog posts, HGH community, social media platforms, sponsored events and news releases. But there’s nothing quite as inspiring as discussing the subject face-to-face with fellow bodybuilders and fitness enthusiasts, as I was reminded during a recent visit to my local gym.

A few days ago, while I was in the middle of my leg workout routine, a guy at the weight machine next to me struck up a conversation. He told me that he used to lift in high school, and was slowly getting back into it again after a lengthy hiatus – and was finding it much more challenging than he remembered. When he noticed my HGH.com shirt, he asked, “Do you use HGH? Does it really work?”

I told him that I’ve been using natural HGH supplements for years; and in a nod to an old TV commercial, I said, “Not only do I run HGH.com, I’m also a client.” He got the reference, and we both laughed. Then I asked him, “You know that HGH and testosterone levels naturally decrease over time, right?” He replied, “Sure, that’s common knowledge. But…isn’t HGH illegal without a prescription?”

This is a question I’ve often been asked by those who are new to HGH; it seems that despite the steadily growing popularity of HGH supplements, many myths and misconceptions still remain. So I went on to explain the differences between prescription-only synthetic HGH injections and over-the-counter natural health supplements that contain HGH releasers. As I saw the awareness and interest dawn in my fellow weightlifter’s eyes, it occurred to me that many others have the same questions – and that I could play a role in educating the public on this topic.

In light of that goal, HGH.com recently issued a news release to the national media spotlighting how legal, non-synthetic growth hormone supplements provide an over-the-counter alternative to HGH injections. And I decided to write this blog post to address the questions I was asked by my new gym friend and by numerous bodybuilders, athletes and fitness enthusiasts before him. Without further ado, here are my answers to the most commonly asked questions about HGH releasers and HGH.com health and bodybuilding supplements:

Why is HGH so popular among bodybuilders and athletes?

Human growth hormone – better known as HGH – is a polypeptide hormone secreted by the pituitary gland. It is essential for growth and development, which is why the highest naturally occurring HGH levels are found in children and teens; and it is also involved in regulating body composition, metabolizing sugar and fat, and building skeletal muscle. After adolescence, HGH levels gradually decrease over time – and that’s where HGH supplementation comes in. Because HGH plays a role in growing and repairing muscle, many athletes, bodybuilders and fitness enthusiasts rely on HGH supplements to help them build muscle and recover from intense training.

How are HGH releasers different from HGH injections?

HGH injections generally involve a synthetic form of growth hormones; each dose introduces HGH directly to the bloodstream through subcutaneous or intramuscular injection. By contrast, most HGH releasers – also known as HGH secretagogues – primarily feature natural ingredients that are consumed orally in capsule, liquid or powder form. Rather than elevating HGH levels with externally manufactured growth hormones, the HGH releasers in natural dietary supplements are intended to stimulate the body to produce more of its own HGH.

Why use natural HGH releasers versus synthetic HGH injections?

I personally prefer natural HGH supplements because I believe they are safer and easier to use than injections, as well as more affordable; and I know a lot of athletes and bodybuilders who feel the same way. Synthetic HGH can be very expensive, and it requires a prescription from a supervising physician. It has also been associated with a number of reported side effects, including joint pain, muscle pain, carpal tunnel syndrome, edema, and numbness and tingling of the skin. And let’s face it – a lot of people simply hate needles, and would rather take supplements orally.

But perhaps the biggest argument in favor of over-the-counter natural HGH supplementation is that the FDA has only approved the use of injectable synthetic HGH for the treatment of specific diseases and medical conditions. Using HGH injections for “off-label” purposes – such as bodybuilding, weight-loss and anti-aging benefits – is considered “illicit”, and is therefore illegal if the synthetic growth hormone was not prescribed by a supervising physician. (The U.S. Drug Enforcement Administration has published a helpful HGH fact sheet with more details on the use and abuse of synthetic HGH.)

Since the majority of herbal dietary supplements are not FDA-regulated, consumers can legally purchase and use non-synthetic HGH releasers for muscle building, weight loss and recovery from intense workouts. And because HGH.com sells natural HGH and bodybuilding supplements rather than injectables, our over-the-counter products can be legally purchased and shipped anywhere in the United States – and in most other countries around the world.

Which HGH releasers are the best for bodybuilders?

HGH.com sells a variety of natural HGH releasers, including many “stackable” bodybuilding supplements that are designed to work together to produce visible results. But if I were asked to suggest just one product for someone who is getting started with HGH supplements, I would recommend our Purity Select HGF MAX supplements. These capsules contain a potent combination of natural ingredients that are formulated to naturally stimulate HGH production. Our proprietary HGF MAX blend includes L-arginine, L-glutamine, L-lysine, L-tyrosine, L-ornithine, glycine, gamma-aminobutyric acid (GABA), phosphatidyl choline, astragalus extract and deer antler velvet. Not only is HGF MAX designed to build lean muscle and aid in muscle recovery, but it has the potential to deliver a host of other benefits: enhanced metabolism and fat-burning capabilities; immune system support; increased stamina; anti-aging effects; more restful sleep; and improved skin, hair and nails. Other popular Purity Select HGH releasers include Somatropinne HGH, DBol-GH, Ana-GH, HGH Testosterone Plus, HGH 30,000 Nanograms Pills and 30,000 HGH Nanograms Spray.

Which HGH releasers are the best for recovery?

Most of the products we feature on HGH.com help support muscle recovery following intense training. If I were to narrow it down to my top three choices for hardcore bodybuilders, I would suggest Purity Select Somatropinne HGH, HGF MAX, and/or Cut and Ripped Plus. However, if anyone has questions about specific supplements or ingredients, we’re happy to provide answers. We have customer services representatives available via phone (888-399-5993), email (support@hgh.com) and live chat. Or you can connect with us on Facebook, Twitter and other online channels.

Any other advice?

Sure; there are a few parting points I would like to share:

  • First, always follow the usage and dosing instructions listed on the HGH supplement packaging. Our Good Manufacturing Practice (GMP) labs carefully formulate the proper dosages of each supplement and explain how and when to take them for optimal benefits.
  • Second, be aware that heat can decrease the potency of certain supplement ingredients. So, be sure to store your HGH releasers in a cool, dry place. And whether you’re using capsules or powdered drink mixes, always take your supplements with cold (or room-temperature) liquids – save the hot beverages for well before or after your supplements.
  • Third, don’t hesitate to reach out to others for help and recommendations. We’re always here to answer your questions, and you’ll likely find that fellow weightlifters at your local gym are happy to share workout and supplement suggestions. Also, you can connect with bodybuilders you admire online. Our HGH.com-sponsored athletes – award-winning IFBB pros Richard “Tricky” Jackson, Ben White and Tara Silzer – regularly provide guidance and advice to their fans and followers. And finally, visit our HGH.com blog frequently; we often publish workout videos, articles and links to helpful resources.

L-Glutamine Benefits, Uses, Side Effects and Functions

Discover the Function, Sources and Benefits of the Health Supplement Ingredient L-Glutamine, or 2-Amino-4-Carbamoylbutanoic Acid

Glutamine – also known as L-glutamine and 2-amino-4-carbamoylbutanoic acid – is considered a conditionally essential amino acid. This means that while the body is usually able to produce sufficient amounts of glutamine for its daily needs, L-glutamine supplementation may be required in instances when glutamine is depleted due to stressors. Illness, injury, surgery, chemotherapy and intense exercise can all deplete glutamine levels. Individuals who need to replenish L-glutamine can obtain it through certain food sources as well as in natural health and bodybuilding supplements such as HGF-MAX, HGH 30,000 Nanograms pills and spray, and whey protein mixes.

Functions of L-Glutamine

Amino acids serve as the building blocks of protein, and glutamine acts as a precursor for protein synthesis. It is primarily produced by and stored within muscle, and distributed to other organs via the bloodstream. L-glutamine is believed to act as a human growth hormone (HGH) releaser, also known as an HGH secretagogue. In addition, glutamine is the major fuel source for enterocytes (intestinal absorptive cells) as well as lymphocytes and macrophages (white blood cells that play a key role within the immune system), and it appears to be required for healthy brain function and digestion. Furthermore, L-glutamine is involved in nitrogen exchange and plays a critical role in removing excess ammonia resulting from protein catabolism.

Sources of L-Glutamine

Dietary sources of glutamine include meat (beef, pork and poultry); dairy (milk, yogurt, ricotta cheese and cottage cheese); egg whites; leafy greens (raw spinach and cabbage); legumes (peanuts and soybeans); and grains (wheat, corn and barley). L-glutamine may also be consumed directly – in powder, tablet, capsule or liquid form – as part of a natural dietary supplement.

L-Glutamine Benefits and Uses

Considering L-glutamine’s role as an HGH releaser and precursor for protein synthesis, and given that glutamine levels typically drop following intense exercise, this amino acid has become a popular ingredient in health and bodybuilding supplements. Rigorous workouts and lifting reduce intramuscular glutamine stores and can weaken the muscles if levels are not replenished. That’s why athletes, bodybuilders and fitness enthusiasts often take L-glutamine supplements to aid in muscle maintenance, promote cell renewal and support the immune system – particularly when undergoing intensive training.

For many of the same reasons, L-glutamine can be a useful dietary supplement for individuals recovering from illness, injury, infections, severe burns and surgery. By strengthening the immune system, L-glutamine helps to fight off infections and neutralize excess ammonia and cortisol in the body. Its role in protecting the gastrointestinal lining may help individuals suffering from inflammatory bowel disease (IBD) or short-bowel syndrome. It can help HIV/AIDS patients avoid weight loss, as it enables the intestines to better absorb nutrients. Evidence also suggests L-glutamine may be beneficial for cancer patients undergoing chemotherapy by helping to combat cachexia (weight loss, muscle atrophy and fatigue) and stomatitis (inflammation and soreness in the mouth).

Side Effects of L-Glutamine and Potential Interactions

L-glutamine supplements are generally considered safe for adults, and no significant side effects have been reported in healthy users. However, L-glutamine may exacerbate symptoms in people with certain medical conditions, including liver disease, hepatic encephalopathy, kidney disease, Reye syndrome, seizures and mania.

Interactions are possible with some medications; for example, L-glutamine supplements may decrease the effectiveness of lactulose and anticonvulsants. There has also been conflicting evidence concerning the use of glutamine for cancer patients; while some studies confirm its beneficial effects, others indicate it may interact with cancer medications or potentially stimulate tumor growth. More detailed safety information on L-glutamine side effects and interactions can be found on WebMD. As with any medication or health supplement, it is best to consult your physician before taking dietary supplements containing L-glutamine.

L-Glutamine Research and Studies

Numerous research studies have explored the impact of L-glutamine supplements on subjects ranging from healthy athletes to critically ill patients. In terms of its efficacy as an HGH releaser, an article published in The American Journal of Clinical Nutrition indicated that a small oral L-glutamine load is capable of raising alkaline reserves and increasing HGH concentration in plasma. Another study cited in Nutritional Neuroscience found that an oral supplement containing L-glutamine, glycine and niacin was shown to enhance HGH secretion in healthy middle-aged and elderly subjects.

According to the Asian Journal of Sports Medicine, researchers found that L-glutamine and carbohydrate supplementation improved the physical performance of athletes during repeated competitions by preventing anaerobic power decrease. An article published in the Journal of the International Society of Sports Nutrition reported that L-alanyl-L-glutamine supplementation provided a significant ergogenic benefit by increasing time to exhaustion during endurance exercise. Animal studies also showed promising results; in Cell Biochemistry and Function, scientists examined muscle damage and inflammation in rats following prolonged exercise and found that L-glutamine supplementation diminished inflammation biomarkers and the inflammatory response.

Other research has explored L-glutamine’s effects from a medical perspective. A meta-analysis published in Current Opinion in Clinical Nutrition & Metabolic Care concluded that L-glutamine has a beneficial effect on infectious complications and reduces the length of hospital stays, and noted that it may reduce morbidity and mortality in critically ill patients. For additional L-glutamine research, refer to the PubMed site sponsored by the National Institutes of Health (NIH).

Whey Protein Benefits, Uses, Side Effects and Functions

Discover the Function, Sources and Benefits of the Health Supplement Ingredient Whey Protein

Whey protein and casein are the two major types of proteins in milk. While casein is digested more slowly, whey is a quickly and easily digested source of protein. It contains essential amino acids, including branched-chain amino acids (BCAAs), and its amino-acid profile is similar to that of human skeletal muscle. While whey protein is naturally found in dairy products, it is also available in a more concentrated form in dietary supplements. These include health and bodybuilding supplements such as CytoSport, IsoBolic, Multi-Pro and Elite whey protein powders.

Functions of Whey Protein

Protein contributes to the growth, development and repair of human tissue, so consuming whey protein can help to support these functions. The amino acids contained in whey protein play a critical role in regulating protein metabolism, and are believed to aid the body in transitioning from a catabolic state to an anabolic state following exercise. Furthermore, studies have suggested that whey protein may decrease fat stores in the body and increase feelings of satiety (fullness), thereby helping to regulate weight and body composition.

Sources of Whey Protein

Dairy products are a natural source of whey protein, which separates from milk during the cheese-making process. Among food sources, ricotta cheese contains the highest levels of whey protein; however, it can also be found in milk, yogurt and other cheeses. When whey protein is extracted and processed for use in natural dietary supplements, it can take one of several forms, including whey powder, whey protein concentrate and whey protein isolate. Of these, whey protein isolate contains the highest protein content, followed by whey protein concentrate and then whey powder.

Whey Protein Benefits and Uses

Consuming whey protein elevates the body’s overall levels of protein and essential amino acids, which help to maintain human skeletal muscles. As a result, whey protein is a popular ingredient in health and bodybuilding supplements, where it is used to increase muscle mass and strength as well as improve athletic performance. Because whey protein appears to decrease fat stores and create feelings of fullness, it is also used as an appetite suppressant and may be included as an ingredient in weight-loss supplements.

Another benefit of whey protein is its ability to lower blood-sugar levels, which may be helpful for individuals with milder cases of diabetes that can be controlled with proper diet and exercise. Whey protein is also used as an ingredient in baby formulas because it is an easily digested form of protein and provides important nutrients needed for growth and development. There are many other purported uses of whey protein – ranging from acid reflux to chronic lung conditions to psoriasis – though evidence in these areas is currently inconclusive.

Side Effects of Whey Protein and Potential Interactions

Whey protein is generally considered safe for most adults; users should follow the recommended dosage and directions listed on dietary supplements. Those who are lactose intolerant or have a known sensitivity to milk may find that some whey protein formulas can cause similar symptoms, such as bloating, cramps, diarrhea or nausea. When taken in high doses, whey protein may cause headaches, fatigue or thirst in some people.

Individuals taking certain types of medication should be aware of potential interactions. Whey protein may decrease the absorption of levodopa, alendronate and some antibiotics (including quinolone, fluoroquinolone and tetracycline). Since whey protein has been shown to lower blood-glucose levels, it can cause hypoglycemia when it is taken in combination with diabetes medications. When whey protein is taken in combination with blood thinners, it may increase the risk of bleeding.

More detailed safety information on whey protein side effects and interactions can be found on the Mayo Clinic website. As with any medication or health supplement, it is best to consult your physician before taking dietary supplements containing whey protein.

Whey Protein Research and Studies

Numerous studies have examined the effects of whey protein on muscle mass, muscle recovery, athletic performance and body composition. For example, recent animal studies published in the journals Nutrition and Medicine & Science in Sports & Exercise found that resistance exercise combined with whey protein led to significant muscle weight increases in rats and that whey protein supplementation improved exercise performance, body composition and biochemical assessments in mice.

Human trials also support the use of whey protein for post-exercise recovery and improved body composition. Research published in Amino Acids determined that whey protein may accelerate the muscle regeneration/remodeling process after high-intensity exercise, while the International Journal of Sport Nutrition and Exercise Metabolism reported that whey protein supplements taken by runners facilitated their recovery from strenuous training. In the Journal of the American College of Nutrition, researchers analyzed 14 randomized, controlled trials on generally healthy adults and found that whey protein supplements – either combined with resistance exercise or as part of a weight-loss or weight-maintenance diet – improved body composition parameters.

In addition, research findings suggest that whey protein supplements are beneficial for overweight and diabetic individuals. In the Journal of Applied Physiology, researchers studied overweight/obese adults who consumed whey protein supplements either with or without exercise and found that all of them lost body weight, fat mass and abdominal fat. Among those test subjects, the group that took whey protein supplements in combination with a multimode exercise training program lost significantly more body weight and gained a greater percentage of lean body mass. An article published in Diabetologia examined the impact of whey protein on diabetics, and determined that taking whey protein before breakfast helped to increase insulin levels and decrease glucose in patients with type 2 diabetes. For additional whey protein research reports, refer to the PubMed site sponsored by the National Institutes of Health (NIH).

L-Leucine Benefits, Uses, Side Effects and Functions

Discover the Function, Sources and Benefits of the Health Supplement Ingredient L-Leucine or 2-Amino-4-Methylpentanoic Acid

Leucine – also known as L-leucine and by its scientific name, 2-amino-4-methylpentanoic acid – is a branched-chain amino acid (BCAA). Because the human body cannot synthesize this essential amino acid, it must be obtained from food sources such as meat, dairy products and legumes. L-leucine is also available in natural dietary supplements, including health and bodybuilding supplements such as Ana-GH, DBol-GH, Cut and Ripped Plus, Amino Shooter and Chocolate Whey Protein.

Functions of L-Leucine

Branched-chain amino acids like L-leucine stimulate protein synthesis by triggering pancreatic islet cells to release insulin. This protein synthesis primarily takes place in skeletal muscle, but also occurs to a lesser extent in the liver and adipose (fat) tissue. It is believed that L-leucine may help prevent or reduce muscle damage, enhance anabolic muscle signaling, lower blood-glucose levels and avoid faulty message transmission in the brain cells of people with certain diseases. It may also decrease serotonin production by blocking tryptophan transport to the brain, thereby reducing feelings of drowsiness and fatigue.

Sources of L-Leucine

According to the United States Department of Agriculture (USDA), common dietary sources of L-leucine include beef, pork, fish, chicken, turkey, eggs, cheese and milk. Legumes are another good source – particularly beans, soy and peanuts – as are nuts and seeds (such as almonds and sunflower seeds) and grains (like wheat germ, oats, corn and rice). L-leucine may also be consumed directly as part of a natural dietary supplement.

Leucine Benefits and Uses

Because of L-leucine’s role in protein synthesis, it is often used in health and bodybuilding supplements that are designed to build muscle strength, increase exercise endurance, reduce muscle breakdown and promote muscle recovery. Its ability to inhibit serotonin production means that L-leucine may help prevent or delay fatigue during exercise. L-leucine has also been shown to stimulate the appetite – making it useful for athletes looking to gain mass and weight.

In addition, L-leucine appears to benefit individuals with specific medical conditions. For example, it may help to lower blood-glucose levels in diabetics, and it can improve the health and nutrition of patients experiencing loss of appetite due to hemodialysis, cancer treatments or anorexia. L-leucine has also been shown to diminish symptoms in manic patients, reduce involuntary movements in individuals with tardive dyskinesia, and improve muscle control and brain function in patients with advanced liver disease, including various forms of hepatic encephalopathy.

Side Effects of L-Leucine and Potential Interactions

L-leucine is generally considered safe when taken in normal doses, such as those found in food and most dietary supplements. However, excessive amounts can result in hypoglycemia or vitamin B3 and B6 deficiencies. Users are advised to adhere to supplement dosing information and avoid consuming more than 39 grams of L-leucine per day.

Few L-leucine side effects have been recorded, though some users have reported experiencing fatigue or decreased motor coordination. Individuals with certain medical conditions – including amyotrophic lateral sclerosis (ALS, or Lou Gehrig's disease), isovaleric acidemia, branched-chain ketoaciduria (maple syrup urine disease) and chronic alcoholism – should avoid L-leucine, as it can pose health risks in these patients. In terms of L-leucine interactions, it appears to decrease the effectiveness of levodopa. Conversely, it can have an additive effect when taken with diabetes medication, potentially resulting in hypoglycemia. Other medications – such as Diazoxide and corticosteroids – can decrease the effects of L-leucine on protein, while thyroid hormone medication can cause the body to break down L-leucine more slowly.

More detailed safety information on L-leucine side effects and interactions can be found on WebMD. As with any medication or health supplement, it is best to consult your physician before taking dietary supplements containing L-leucine.

L-Leucine Research and Studies

Scientists have researched L-leucine and other BCAAs to determine their benefits and practical uses, and numerous studies have indicated a positive effect on muscle strength, exercise endurance and muscle recovery. An article published in the European Journal of Applied Physiology reported that outrigger canoeists using leucine supplements displayed significantly improved endurance performance and upper-body power. In Applied Physiology, Nutrition, and Metabolism, researchers noted that well-trained male cyclists who took a leucine-protein supplement after intense training subsequently exhibited improved high-intensity endurance performance and lower perceived levels of tiredness. And according to the Journal of Sports Science & Medicine, resistance-trained males who consumed an energy drink with leucine (and other key ingredients) prior to their workout demonstrated a significant increase in the number of repetitions successfully performed.

Other studies examined the impact of L-leucine on protein synthesis. Research findings published in The American Journal of Clinical Nutrition indicated that increasing the concentration of leucine in an essential amino acid supplement consumed during steady-state exercise resulted in a greater muscle protein synthesis response during recovery. And in The Journal of Nutrition, researchers determined that insulin and leucine work in synergy, allowing skeletal muscles to coordinate protein synthesis with physiological state and dietary intake.

For additional research related to L-leucine, refer to the PubMed site sponsored by the National Institutes of Health (NIH).
