Anabolic Steroids

When I look at today's baseball players, I just can't believe how big they are. They are larger and stronger than the best players of the 1930s to 1970s. Babe Ruth, arguably the greatest hitter who ever lived, was a fat elephant with relatively small muscles and a huge belly compared to the average player today.

Anterior Cruciate Ligament (ACL) Tears

The anterior cruciate ligament runs from the top bone of the knee to the bottom one and prevents the top bone from sliding forward when the foot hits the ground during running and walking. If it is torn, the knee becomes so unstable that a person will have difficulty walking, so all torn anterior...

Rotator Cuff Injuries

The rotator cuff muscles hold the head of the long bone of your upper arm tightly in the socket of your shoulder. Sports that require moving the arm over the head repeatedly can cause tearing and swelling of the tendons of these muscles. Baseball pitchers, swimmers, weight lifters and tennis players often suffer this...

How To Run Faster

If you don't run very fast in practice, you won't be able to run very fast in races.

How to do the Most Pushups

If you want to be able to do 100 pushups in a row, do not try to do as many pushups as possible every day. You'll probably injure yourself and end up unable to do any pushups at all. Training for competition requires an understanding of the stress- and-recover rule and the interval-sets rule. The...

Belly Cramps During Exercise

The most common cause of belly cramps during exercise is having a full colon. The best way to prevent exercise-induced belly cramps is to completely empty your colon before you start to exercise. Belly cramps are rarely caused by having food in your stomach. To meet their energy needs, bicycle racers have to eat...

Lifting Weights Won’t Make You Musclebound

Training for strength improves coordination. Your brain is a master switchboard that coordinates your muscles. Lifting weights does not interfere with brain function; it improves coordination in events that require strength, such as playing sports, working as a carpenter, opening a stuck door or beating a drum.

Electronic Ab Machines

Your brain does send an electrical impulse along nerves that enter muscles to cause them to contract. The electrical impulses generated by ab machines are so weak that they can't possibly cause contractions that strengthen muscles significantly. If they did give you enough electricity to strengthen your muscles, they would give you a very painful shock.

Eat Carbohydrates During Competition, Not Fat

Taking extra fat during long distance running or cycling races will not help you to go faster or win the race. When you exercise intensely, your muscles burn mostly sugar and the more intensely you race, the greater the percentage of sugar that your muscles use.

Spinning Classes

Whether you're out of shape or very fit, spinning classes can help you improve. You ride a stationary bicycle in a group, with a leader who tells you what to do and plays lively music to set the tempo. Many health clubs and gyms offer these classes, and I recommend them to all of...

Slow Lifting

If you want to become very strong, you have to lift weights heavy enough to make your muscles burn. It doesn't make any difference whether you move the weights slowly or rapidly. Just exercise intensely enough so your muscles feel sore the next day.

Sit Ups for Belly Strength

Sit ups strengthen your belly muscles, provided that you know how to do them. Lie on your back with your knees bent with your soles on the floor. Place your hands on your chest and slowly raise your head off the ground. Then, slowly raise your shoulders off the ground to a height...

How to Pedal a Bicycle

You should pedal with the ball of your foot, not your arch. The ankle is the fulcrum for the force you generate with your feet. The ball of your foot is further away from the ankle than your arch so you generate far more force with the ball of your foot. As you straighten your...

Should You Carry Weights during Exercise?

The only advantage to exercising while carrying weights is that you can get more exercise while moving slowly. To strengthen your heart, you have to exercise vigorously enough to increase your heart rate at least 20 beats a minute above resting.

Mamo Wolde, Olympian

Mamo Wolde died recently at age 71. At 36, He won the 1968 Olympic marathon and the 10,000-meter silver medal in Mexico City. He spend the last part of his life in prison. He was buried with a guard of honor of some of the greatest distance runners who ever lived. In 1960, his...

Ankle Weights Won’t Help You to Run Faster

Ankle weights do not help you run faster or jump higher. To run fast in competition, you have to run fast in practice. Ankle weights slow you down because they interfere with your coordination and make you work much harder to raise your knees. To jump higher, you have to strengthen your leg muscles...

Triathalon Training

Will training for a triathalon make you a better cyclist? World-class triathletes are slower runners, swimmers and cyclists than athletes who compete in only one sport. A study from the University of Toulon-Var in France shows that swimming before cycling slows you down (Canadian Journal of Applied Physiology, August 2005). Well-trained male triathletes pedaled...

Hypothermia

In 1812, Napoleon attacked Russia with 453,000 men, but after he withdrew from Moscow, the harsh cold winter reduced his "Grande Armee" to fewer than 10,000 fighting men. The vast majority of Napoleon's soldiers were not killed by the Russians. They died of hypothermia, a severe drop in body temperature. If you dress properly...

Prepare for Skiing

The best way to train for skiing is to ski, but snow isn't always available. To prepare for a skiing vacation, you need to strengthen both your heart muscles and your skeletal muscles. You can strengthen your heart for skiing with any exercise that will raise your heart rate for at least 10 minutes,...

How to Jump Higher

When Kent Benson, the former National Basketball Association player, came to the University of Indiana he could jump only 9 inches off the ground. That's an embarrassing jump for a seven-foot All-American. One year later, he was able to jump three times that high because he had a good coach. How high you can...

Spot Reduction Doesn’t Work

You'll see lots of exercise programs, devices and machines in television commercials that claim to get rid of fat from your belly. While they can strengthen your belly muscles, there is no such thing as spot reduction. When you take in more calories than your body burns, you store them as fat. Some people...

Jump Higher

When former NBA player Kent Benson arrived at the University of Indiana he could jump only nine inches off the ground. That's an embarrassing jump for a seven-foot All- American. One year later, he was able to jump three times that high because he had a good coach. How high you can jump is determined...

Prepare for a Marathon

Many marathon runners think that they have to run 100 miles a week to compete successfully, but most will be able to run a marathon faster if they run fewer than 50 miles a week. Top marathon runners can run 100 miles a week and not be injured because of their superior genes.

Muscle Stimulating Machines

Advertisements on television claim that you can wrap a special belt around your belly, plug it into an electric outlet, turn on the electricity, and then watch your belly muscles contract to give you rock-hard belly muscles. You can bet that the beautiful people who demonstrate the machines on television didn't get their belly muscles...

Helmets Save Lives

A study from Imperial College in London shows that increased use of helmets by bicycle riders has markedly reduced head injuries (1). Do you know why woodpeckers don't damage their brains when they peck on wood? Their skulls fit so tightly that they don't allow the brain to move inside. Human skulls are enclosed...

Exercising in Air Pollution

It's healthy to exercise and harmful to breathe polluted air. Many people wonder if they will do more harm than good by exercising on days when the air is heavily polluted. The worst time for pollution is when clouds cover the sky and automobiles fill the roads. Automobile exhaust fumes are the principal source of...

Prepare for Skiing When There’s No Snow

The best way to train for skiing is to ski, but snow isn't always available. You ski by bouncing up and down on your knees and shushing forward from your hips, so the best sports to prepare for skiing stress primarily your thigh and upper leg muscles: skiing, skating and cycling. Running strengthens your...
