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.

Exercise Choices for the Out-of-Shape

Sixty-five percent of people who start an exercise program drop out in the first six weeks, often because of injuries. Jogging and running are high-injury sports because your feet hit the ground with a force greater than twice your body weight. Pedaling and swimming are safer because you pedal in a smooth rotary motion and when you swim, the buoyancy of the water dampens forces on your muscles.

Get Stronger in 30 Minutes a Week

Most competitive bodybuilders spend hours trying to do many sets over and over again. You don't need to do that. Various studies show that you can gain up to 80 percent of your maximum strength by picking out four to eight specific lifts, lifting one set of ten of the heaviest weight in each, and repeating your program two or three times a week.

Dizziness in Athletes

Knee Injury Rehabilitation

You are supposed to exercise. It makes you stronger, faster, healthier and may even prolong your life. However, every time you exercise, you risk injury and many sports injuries last forever. Depression, heart attacks, strokes, obesity and diabetes are all associated with a sedentary lifestyle. A twisted ankle can change an active person into a sedentary one. A torn anterior cruciate ligament or meniscus of the knee has a greater than 50 percent chance of causing permanent pain within five years, regardless of the treatment.
