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.

People who engage in very repetitive tasks such as long distance running, labor or swimming show very little or no improvement in the size and strength of their muscles. Long distance events are by nature very low in intensity.

Compare a marathon runner to a 100 meter sprinter. Marathon runners who train for very long periods at a very low intensity are emaciated looking having less than normal muscle mass and carry on average 14 ? 16% body fat. Sprinters, on the other hand, who train for short periods at a high level of intensity are very muscular and have half the body fat levels than marathoners. If cardio is the key to getting lean, as many people presume, why do marathoners have a higher body fat than sprinters? The reason is, a specific stimulus is required for a specific outcome.

The specific stimulus needed to stimulate muscle and strength is high intensity training. This is a universal training principle that affects everyone without exception. This is due to the fact that we are anatomically and physiologically the same. If this were not true doctors could not perform surgery and prescribe medicine. Consequently, the stimulus needed to induce biochemical changes that build muscle and strength in humans is the same.

Intensity, when referring to training, is the percentage of physical exertion that one is capable of. Training with one hundred percent intensity is the best way, the only way, to stimulate muscular size and strength in the shortest amount of time. How does one gauge the intensity of their workouts? By taking your working sets to positive or concentric failure.

Taking a set to the point of failure, where you cannot possibly perform another rep despite your maximum effort is one of, and perhaps the most important of several factors in your success. There are many who disagree and advocate high volume training with 60%, 72%, 95%, or whatever percentage of intensity they decide is the best. Some even claim training all out, with one hundred percent intensity is not only unnecessary, but detrimental. Over the years I’ve seen so called strength coach specialists, and personal trainers with 15 letters after their last names, concoct the most ridiculous routines, using almost every percentage, that have yet to show any effectiveness in real world application.

The main problem with these bogus routines is that there are only two accurate measures of intensity. Zero, when you are at rest; and 100%, when you?re training to the point of failure. How do you measure anything less than 100% intensity? If I can do 10 repetitions to complete failure with 100 pounds on the leg extension machine, where do I go for 80% intensity? Do I perform 10 reps with 80 pounds? Or do I use 100 pounds and only perform 8 reps? Is 80% the optimum percentage, or is it 65%? There is no evidence that suggests, let alone proves, anything less than 100% effort is equally or more effective. Are you starting to see the ridiculousness and inaccuracy of such training prescriptions?

Intensity cannot be measured accurately with reps or weight. While performing a set, intensity increases exponentially with each successive rep. Performing the first 5 reps on the leg extension is not equivalent in intensity to performing the last 5 reps. Hence, 5 reps is not the equivalent of 50% intensity.

The only way to train that is completely accurate is with all out intensity to failure. This will give you a concrete view of how you?re performing. If you train with 100% intensity during every workout and you do not progress, you know you are not recovering. There will never be a question whether you are providing a strong enough stimulus for progress. However, if you follow the percentage of intensity or the percentage of max rep principles, how will you know you are training intensely enough to stimulate muscular size and strength? If you plateau, are you training too hard or too long? Do you lower the percentage or raise it? Do you need more rest, or do you need to train at a higher intensity? There is no need for this guessing game.

Your goal is to bring about the largest, most rapid outcome for your individual genetic potential. In order for this to occur, the body requires 100% intensity every working set of every exercise. This is the only truly accurate way to gauge the efficacy of your training program. Nothing less than 100% will do. The body needs a reason to adapt. Give it!

Any type of exercise is good exercise, but some forms of exercise are better for greater weight loss than others. Group sports, and other types of exercise that work the body from head to toe, burn hundreds of calories per hour and they also challenge all muscle groups. Not only can this help you lose more weight, it can also help you keep it off. Just a few uber effective forms of exercise are swimming, cardio boot camp, running, basketball, and racquetball.

Racquetball is similar to handball. The game is played on a four walled court with a short-handled racket and a larger ball. The game is usually played by two players, but four players is also common. The amount of calories burned during an hour long game varies by weight and whether or not the game is casual or competitive. To give you an idea of just how many calories you can burn, a person that weighs 125 pounds can burn around 400 calories during a casual game or 568 calories during a competitive game. A 170-pound person can burn 541 calories during a casual game or 773 during a competitive game.

Racquetball can help you lose weight if you make smart food choices and commit to playing at least three times a week. Once you lose the weight, if you want to keep it off, stick to a sensible diet and try play on most days of the week.

So where are the Racquetball Courts?

If you’re looking for a place to play racquetball, look no further than your local health club, tennis club, community center or park district. If you’re looking for the cheapest place to play, try a community center or park district where public courts are typically no more than $10 an hour.

Laura London burst onto the fitness scene a little more than a year ago and has been on fire ever since. This spicy and super sexy 5’ 2” 45 year old wife of 20 years and mother of three shows us that age has no barrier on fitness. What Laura has accomplished in the past year is just short of amazing.

there are many biological factors that are important for muscular hypertrophy like hormone levels, age, sex, muscle fiber type, diet, among others. These factors have been recognized as extremely important for the hypertrophic adaption to strength training. Many of these factors, however, are known to vary throughout the day. Can the daily differences in the above factors like hormone levels, affect the adaptive response to strength training? What time of day is the best time to train?

A study published in the Journal of Strength and Conditioning Research set out to examine the effects of time-of-day-specific strength training on muscle hypertrophy maximal strength in men. The training group underwent a 10 week preparatory training regimen. Afterwards, the subjects were randomized to either a morning training group or an afternoon training group. The groups trained for another 10 weeks with training times between 07:00 and 09:00 hours and 17:00 and 19:00 hours in the morning group and the afternoon group respectively. Cross-sectional areas and volume of the quadriceps femoris were obtained by magnetic resonance imaging at weeks 0, 10, and 20. Maximum voluntary isometric strength during unilateral knee extensions and the half squat one repetition maximum were tested at weeks 0, 10, and 20.

The entire 20-week training period resulted in significant increases in maximum voluntary contraction and 1RM in both training groups. In this study, the magnitude of muscular hypertrophy and strength did not statistically differ between the morning or afternoon group. However, this study was of short duration and like most research concerning physical improvement through exercise, there needs to be more subjects over longer periods of time.

Some like them light, others like them heavy and some like them somewhere in between. No matter what you prefer, there’s a gym shoe out there just waiting for you, all you have to do is walk into the athletic store and let your feet do the rest. Just in case you’re unsure about what your feet (and your body) need to be comfortable, here’s what you should look for:

A specific shoe for a specific activity.
It’s never a good idea to purchase a pair of gym shoes that are made for walking if you’re planning to run. Walking shoes tend to be stiff, while running shoes are flexible with extra components such as cushioning to handle higher levels of impact. Running in walking shoes can lead to aching heels, shin splints, and muscle aches.

Shoes that fit your foot type and no one else’s.
Some us have flat feet, others have narrow feet, and some of us have wide feet. Never try to stuff your wide feet into a narrow pair of gym shoes because they look good. You’ll end up with more than just aching heels at the end of the day. A good shoe store will have all the equipment it needs to measure your foot precisely, and match you with the perfect shoe. Listen to the salesperson’s suggestions and you won’t be sorry later. Here’s another tip, foot size continues to change as we age, so have your feet measured twice a year.

Wiggle room.
Ok, so of course you need extra room for socks, but you’ll need even more room to wiggle your toes. Yes, gym shoes should not be snug at the front, but your heel shouldn’t slip out of the shoes either. Leave at least 3/8-1/2 inch between the front of your big toe and the inside of the front of the shoe for a comfortable fit. You shouldn’t feel any tightness anywhere. If you do, keep trying until you don’t!

Cutting-edge components for whatever ails you.
Having trouble getting shoes to fit no matter what you do? Try a pair that allows you to pump up the tongue for a customized fit. Got heel pain? Try a pair of gym shoes that come with clear inserts or shoes that are filled with gel, air, or Freon. These components add extra shock absorption, so you’re feet are less likely to hurt after a vigorous workout.

Mileage.
Yes, shoes rack up the miles, just like a car. And, like a car, they can break down when they’ve racked up too many. Ask the salesperson how many miles your shoes will last. The figure should be somewhere between 350 and 400 miles. Once your gym shoes hit the mark, it’s time to trade them in for a new pair. If you just don’t have time to calculate miles, it’s ok. You can go by how your shoes look and feel. If the shoes no longer offer support, they’re uncomfortable, or the back heel is worn out, it’s time to throw those puppies out and buy a new pair.

46 million adults have been diagnosed with arthritis. 9% of these individuals claim arthritis limits their physical capabilities; 21 million people alone suffer from osteoarthritis. Unfortunately, the incidence of arthritis is on the rise, but there are things you can do to ease the symptoms.

Exercise can be a great way to deal with the aches and pains of arthritis. But it’s important to perform the right exercises under a doctor’s supervision.

Here are suggestions about exercising if you have arthritis, courtesy of the University of Washington School of Medicine:

• If you have a physical or occupational therapist, he or she should participate in creating your exercise plan.
• Your exercises should put minimal stress on your joints, especially when you first start out. Don’t overdo it.
• Try a combination of both therapeutic (designed to help ease symptoms and improve joint function) and recreational (just for fun) exercises.
• Use other methods to ease symptoms, such as using heating pads and ice packs, eating a healthy diet, taking medication as prescribed, and maintaining a healthy body weight.

Exercise induced endogenous hormone levels have been studied extensively. Researchers have examined how the different components of training including sets, repetitions, load and rest intervals affect serum levels of hormones such as testosterone, growth hormone and cortisol. Many studies have demonstrated there is an acute increase in serum levels of anabolic hormones after intense resistance exercise.

To be more specific, high intensity exercise coupled with short rest intervals that is performed with large muscle groups are associated with large rises in these hormones when compared to other training methods. Conversely, training small muscle groups like the biceps has been shown to have no effect on serum hormone levels. Because of the findings in many studies, training programs have been constructed to maximize the post-exercise rise in these hormones based on the assertion that exercise-induced increases in hormones like testosterone and GH will enhance muscle size and strength. But, considering the fact that these increases in hormone levels are very small and of short duration, will they produce muscular gains.

A study from the Kinesiology Dept. of McMaster University in Canada found that exercise induced hormone levels had no effect on muscle size or strength after 15 weeks of resistance training.

There is evidence that a minimal basal level of testosterone is required to support strength and hypertrophy gains, which are otherwise attenuated. Therefore, the hormone-sensitive processes that underpin muscle anabolism at hypo- and supra-physiological hormone levels are not being activated appreciably by exercise-induced increases in hormone availability or at least do not result in any measurable enhancement of strength or hypertrophy.

Saunas are everywhere—at health clubs, spas, in hotel rooms, in apartment communities, rehabilitation centers, sports complexes, swimming pools, and in private homes. The reason saunas are so popular is simple. Lying in a sauna is a great way to relax and unwind, but did you know that saunas are not only good for mental health, but they may also be good for physical health too? Some may disagree, while others offer a convincing argument for using saunas for detoxification, weight loss, cellulite reduction, pain relief, the treatment of respiratory problems, and to help clear skin problems. So how does relaxing in a sauna accomplish all of this? According to Fuller Fitness:

During a 10-20 minute sauna session, your heart rate increases by 50-75%. This provides the same metabolic result as physical exercise. The increased cardiac load is the equivalent to a brisk walk. There is a nominal effect on blood pressure because the heat also causes blood vessels in skin to expand to accommodate increased blood flow.

Blood vessels become more flexible and there is increased circulation to the extremities. During a sauna, blood flow to the skin increases to as high as 50-70% of cardiac output (compared to the standard 5-10%). This brings nutrients to subcutaneous and surface tissue resulting in glowing healthy skin.

Steambaths and saunas induce sweating to provide a comprehensive cleansing of the skin and sweat glands. Skin is the largest organ in the body. Thirty percent of body wastes are passed through the skin. Profuse sweating enhances the detoxifying capacity of the skin by opening pores and flushing impurities from the body.

When taking a sauna, skin temperature rises to 40°C (104°F) and internal body temperature rises to about 38°C (100.4°F). Exposure to the high heat creates an artificial fever state. Fever is part of the body’s natural healing process. Fever stimulates the immune system resulting in increased production of disease fighting white blood cells, antibodies and interferon (an anti viral protein with cancer fighting capability).

Spas and other such therapeutic facilities utilize saunas and steambaths in conjunction with massage to loosen fatty tissue and assist in the battle against cellulite.

The cleansing effect of profuse perspiration helps provide healthy skin and a clear complexion.

Before using a sauna, there are a number of precautions to follow. Harvard Men’s Health Watch offers the following advice:

·Avoid alcohol and medications that may impair sweating and produce overheating before and after your sauna.
·Stay in no more than 15–20 minutes.
·Cool down gradually afterward.
·Drink two to four glasses of cool water after each sauna.
·Don’t take a sauna when you are ill, and if you feel unwell during your sauna, head for the door.

Many people can tolerate the intense heat in a sauna, while others cannot. If you have high blood pressure or a cardiovascular condition, check with your doctor to make sure it’s ok to use a sauna.

We’ve all heard about the “After Burn” effect of exercise.

That coveted condition where the body continues to burn calories long after we’ve finished working out.

Well, it seems that science may have proven that this does indeed happen and at a higher and more intense rate than expected.

Studies which are done properly (many are not), find that extra calories are burned in the hours after exercise — but only if subjects exercise hard and long; intensely for 45 minutes.

And if they exercise even harder, they burn even more calories afterward.
