We all know that exercise is good for our health. Exercise helps to improve our cardiovascular system, and respiratory system; resistance exercise helps to improve muscle function and will prevent age associated muscle atrophy. But did you know exercise, especially high intensity exercise by flooding it with free radicals. Free radicals are chemical marauders that can affect every cell in your body causing DNA mutations, premature aging, cell death, muscle weakness, fatigue and chronic oxidative stress.
So how can you get the best benefits of regular exercise—without placing your body at risk in the process? Proper antioxidant support is one effective way: Extensive research shows that safe, natural substances including vitamins A, C and E, N-acetyl cysteine, lutein, rosemary leaf extract, turmeric, green tea, bilberry and grape seed extract are all potent free radical quenchers—and you can find all of them in a single daily formula from Vitamin Research Products called Extension Antioxidant.6-15
Supplementing with nutrients that will help your body to replenish its essential ATP levels is another key strategy—one that will improve muscle function plus increase your heart’s stamina and help it to keep up with the demands for more ATP during exercise.16
D-ribose is a pentose sugar that can help to maintain ATP regeneration in your body, especially following exercise. Studies document that D-ribose can supply extra amounts of ATP to your heart muscle in particular.17-18 Meanwhile, the popular antioxidant coenzyme Q10 (CoQ10) also plays a vital role in ATP synthesis, and can improve energy production when your body is under physical stress.19 It’s no surprise, then, that research shows that regular CoQ10 supplementation can boost exercise tolerance, lessen fatigue and improve physical performance in active subjects.20-23
Whether you’re a casual exerciser or an amateur athlete, look for the highly bioavailable form of CoQ10, preferably the second generation CoQ10-H2™, to combine with Extension Antioxidant and D-ribose—which are all available from VRP—for a supplement-based strategy that can reduce your recover time plus maximize your strength, energy and endurance throughout each and every workout.
When most think of carbohydrate loading, the classic method of low carb consumption coupled with bouts high intensity exercise followed by a high intake of carbs a few days before competition comes to mind. The result, according to the theory, is super-compensation of glycogen storage in the muscle cells and liver. The theory holds that one must deplete their glycogen stores prior to consuming or loading carbs in order to facilitate super-compensation.
The average person’s total amount of muscle glycogen is approximately 300 – 500g depending on their gender, size, and level of training. The liver stores between 60 and 120g. A linear relationship exists between the depletion of muscle glycogen and fatigue during exercise. With less glycogen to produce glucose, hypoglycemia begins to affect the athlete. Typically, a person with a blood glucose level below 70 will start to feel light headed, lethargy, and have cold clammy skin. A highly trained athlete, on the other hand, can train at much lower levels than 70 for long periods of time.
As with all training topics there is conflicting evidence on what is the best method to achieve super-compensation of glycogen stores. studies are reporting similar results to the classic method, which so many athletes swear by, without carb depletion, while tapering their training (1,2,3). One thing is for sure, carbohydrate levels play a key role in training and competition success.
In order to figure out what works best for you, try different methods and keep a detailed journal. We all process carbs the same way, but we metabolize them at different rates. Keep mind, studies on training are by no means the end all be all. There are too many variables in most training studies to be reliable. Athletes, especially endurance athletes are over-trained. It is my opinion that athletes who are achieving super-compensation without depletion coupled with bouts of intense training, are doing so because they are over-trained and under-fed before starting the process.
The body is constantly working to stay in homeostasis. Physiology shows us glycogen storage is finite; the body needs a reason to super-compensate. Achieving a glycogen depleted state over a period of time produces an insulin sensitive environment, which is essential for more than normal levels of glycogen storage.

Are you interested in getting in shape and losing some weight but you’re bored and find it hard to get motivated. Do you need something new, something exciting? The RealRyder just might be what the doctor ordered.
The RealRyder was released earlier this year and is revolutionizing indoor cycling. The RealRyder ABF8 vision began 15 years ago when competitive cyclist and RealRyder International co-founder, Colin Irving, saw a need to improve the performance of the stationary bike to simulate the real bike experience. Colin shared his dream and joined industry expert Sean Harrington, whose fitness contributions include the Heart Mate Stationary Bike, and pioneering of Nautilus as a successful fitness club chain operation, to bring this product to market. Rich Hanson, who helped bring the Stairmaster to market, is also largely involved in RealRyder and its current success.
Unlike fixed stationary bikes, the RealRyder Indoor Bike has a patented articulating frame which allows the user to ride fluidly in three dimensions. The RealRyder leans 45 degrees to the left and right which simulates turning and banking on the road so you can get the benefits of riding outdoors, inside. Riding indoors is no longer just a leg workout, it’s a total body experience.
We all recover from exercise at different rates. Many people who recover quickly have reached a high level of success performing a high number of sets. Many who recover slowly have also been very successful performing low numbers of sets. Because everybody is unique in their ability to adapt and recover from different programs, the number of sets needs to be individualized.
A very important component of a training program that should be given consideration is training frequency. How often can, or more importantly, should I train per week? Optimum recovery time between training sessions is essential if one is going to continue to make progress. Training frequency, which is determined by ones recovery ability, is often a forgotten part of most training protocols.
Don’t be so concerned with how many training sessions you can handle per week. Be more concerned about the optimal amount. More is not always better. In fact, when somebody comes to me for advice because they’ve stopped making progress, usually I either reduce the workout volume or add days off. There is no reason to go to the gym if you’re not going to make progress.
Does it make sense to keep doing the same routine if gains are not being made? Isn’t the definition of “crazy”, doing the same thing over and over expecting different results. If your current program is not working, change it. The number one complaint people have is they’re not making progress or their progress has come to a halt. In both cases, the answer is more recovery time. Understanding the fact our bodies have a finite amount of recovery ability should help explain this concept.
The following is Mike Mentzer’s explanation of overtraining and recovery. I’m sure you’ll find it interesting.
In bodybuilding, the idea is to impose a training stress onto the body that will serve to induce the biochemical changes which result in muscular hypertrophy. Applying any more of the training stress (high-intensity) than is required by nature will result in the equivalent of over-dosing on a medicine; or, as we say typically in bodybuilding – overtraining.
A person exposed to the sun’s ultraviolet rays at the equator in summer would not have the slightest concern whether the intensity of the sunlight stress is high enough to disturb the physiology sufficiently to induce an adaptive response, i.e., the buildup of a suntan. His only concern, his overriding consideration, would be to properly regulate the volume (or duration) and frequency of exposure time so as not to overdose on the stress/stimulus; and, thereby, incur a sunburn or, in extreme cases, death. A person seeking to develop a suntan at the equator, or wherever the intensity of the sunlight is high has no concern that he will develop a suntan; but only if he doesn’t overexpose. (Note that bodybuilding science is largely based on the medical discipline of stress physiology. Also, that the end result of the healing of a sunburn is not a suntan, just as the end result of the healing of overtraining is not greater strength or added muscle.)
As the stresses grow progressively greater, they will eventually reach a critical point such that they constitute overtraining. The first symptom will be a slow down in progress; and if the individual continues with the same volume and frequency protocol, the stresses will continue to increase until there is a complete cessation of progress, typically referred to as a “sticking point.” One need not ever experience a slow down in progress, let alone a sticking point, if he bears in mind all the while that as the weights grow progressively greater so do the stresses; and he must do certain specific things to compensate for them.
How often can, or more importantly, should I train per week? Optimum recovery time between training sessions is essential if one is going to continue to make progress. Training frequency, which is determined by ones recovery ability, is often a forgotten part of most training protocols. It never ceases to amaze me how many people train for months and years experiencing little or no success, and never consider the fact they may be doing too much.
Don’t be so concerned with how many training sessions you can handle per week. Be more concerned about the optimal amount. More is not always better. In fact, when somebody comes to me for advice because they’ve stopped making progress, usually I either reduce the workout volume or add days off. There is no reason in going to the gym if you’re not going to make progress. In every workout, if you have fully recovered, and you come ready to work, you should make progress, which is gauged by your strength.
How can anyone get stronger every workout? One can only bench press so much. Eventually, you have to hit a plateau. This is true. If one stays with the same exercises, the same number of reps and the same number of sets, progress may eventually stop. If the proper changes aren’t made at the right time, eventually the body adapts to the stimulus. And this is where the “art” of program design comes to play.
It’s easy to follow a workout. The real challenge is assuring the stimulus is sufficient and more importantly, you recovery from workout to workout so that progress continues over a long period of time. Sometimes this entails having the discipline to deviate from something that is not working. If you’re not making progrss, and you’re training with all out intensity, try taking an extra day off.
A training program in the form of progressive resistance exercise builds muscular size and strength. In order for a training routine to be productive, however, it must first provide the correct stimulus to induce an adaptive response. Second, a workout that stimulates and adaptive response must provide for recovery. Third, in order for recovery and subsequent size and strength increases to occur, nutrients, which are of limited supply in our bodies, must be provided. It is clear that the most important nutrient for recovery is protein. In particular, essential amino acids contained in complete protein sources; dairy, meats, and fish. It is well documented that essential amino acids consumed before, during, and after resistance training boost strength and size gains.
HMB is a metabolite of the essential amino acid L-leucine. During many studies on protein effects, L-leucine seemed to be the single greatest contributor to muscle protein synthesis. A recent study examined the effects of an essential amino acid based product, Muscle Armor (MA); manufactured by Abbott Laboratories contains beta-hydroxy beta-methylbutyrate (HMB).
Seventeen healthy men were randomly assigned to one of two groups and performed twelve weeks of periodized heavy resistance training while supplementing with either MA or an isocaloric, isonitrogenous placebo (Control group (CG)). Every two weeks the subject’s strength and power were measured and blood was drawn. More-over the blood draws taken were performed pre, mid and post-training. Researchers found the MA group affected training induced changes in muscular size and strength to a significantly greater extent than the CG. Also found, was reduced levels of circulating muscle damage markers creatine kinase and malondealdehyde compared with the CG. In addition, the MA group experienced increases in resting and exercise-induced testosterone and resting growth hormone levels with reduced pre-exercise cortisol levels.

1. Running will give you a heart attack or other heart problems. It is true that exercise temporarily raises the odds of a heart attack while you’re mid-workout, but doing it consistently reduces that risk over the long haul, leading to a net benefit. Some researchers have questioned whether marathon running, especially in people who haven’t trained a lot, might cause heart damage, at least temporarily. But there’s no evidence that it causes long-term harm or actually leads to heart attacks. Even athletes with enlarged hearts—if they’re healthy hearts—aren’t, as once feared, at risk of early death. The bottom line: Simply going for a run most days of the week is doing far more good than bad for your heart.
2. Running will ruin your bones and joints. A study in the August issue of the American Journal of Preventive Medicine found no evidence of accelerated rates of osteoarthritis among long-distance runners when compared with healthy nonrunners. “We used to say that osteoarthritis came from wear and tear. That’s now revised to say that is can result from tear but not wear,” says James Fries, emeritus professor of medicine at the Stanford University School of Medicine and senior author of the study. Moreover, weight-bearing exercise like running helps stave off osteoporosis by maintaining bone mineral density.
3. Running will kill you before your time. According to a study published this week in the Archives of Internal Medicine, running and other vigorous exercise in middle age is associated with a longer life. Not only that, it will make your later years more pleasant by reducing disability. After tracking runners and healthy nonrunners for 21 years, starting when they were at least 50 years old, a research team led by Stanford’s Fries found that the ability to perform activities of daily life like getting out of a chair and walking was better among runners than nonrunners. And 19 years into the study, 15 percent of the runners had died, compared with 34 percent of the nonrunners. USNews.com
A correspondent from Men’s Journal recently experimented with a high-altitude simulator to gage its effectiveness. For those unaware, a high-altitude simulator is a tent that engulfs your bed to help increase red blood cell production while you sleep. Why the hell would you want to do that? Well, red blood cells fuel endurance for when we run, swim, bike or do any other fast-paced exercise. Athletes like cyclist Lance Armstrong use it while training for a race because it helps simulate the altitude at which your red blood cells need to increase. Coupled with regular training, it’s like gaining all the benefits from weekly cardio…but while you sleep.
The product is intriguing, because according to the Men’s Journal correspondent, the tent works:
After three weeks, I felt as if I had a third lung. I blazed through a three-mile time trial 5 percent faster than I ever had, and I finished top-15 in my category in a hill climb. During the race I quickly caught my breath on the flat spots, then felt ready to pound away again. The tent worked — but I still had to train hard.
Two questions:
1) Is it worth $1,000-plus and sleeping in a bubble nightly to improve endurance?
For millionaire athletes, a thousand dollars for one of these puppies seems like a bargain, but what about for the common triathlon athlete or endurance enthusiast? Before dismissing the theory, how much do you spend yearly on food, supplements and training equipment to enhance your physique?
2) Are athletes like Armstrong cheating?
We as a society hate the fact that Barry Bonds could break a home run record he unfairly achieved, but are we being hypocritical? If these tents do work, did Armstrong have an unfair advantage? Steroids help testosterone growth, which therefore aids strength and muscle development through exercise. These tents are designed to increase red blood cell production, which therefore aids in endurance through exercise. The connection between these simulators and steroids might be on a different level, but it does raise an interesting debate.
Many physicians, including those whose study was published in the journal Circulation, believe there is such a thing as too much exercise. 60 Boston Marathon participants were screned before the 2004 and 2005 races. They showed normal cardiac function.
The same subjects were tested again after the races. 60% of them had elevated troponin levels. Troponin is a marker in the blood used to help diagnose a heart attack, and to detect mild to severe heart injury. Troponin tests are ordered primarily for people who have chest pain to see if there is damage to the heart. 40% of the participants who had elevated trponin levels had levels at or above the decision limit for acute myocardial necrosis. Meaning, some heart tissue, as in a heart attack, possibly died.
Conclusion: DON’T OVERDO IT. Extreme endurance events are associated with cardiac dysfunction in several studies, especially for those with less training.
