Three Common Myths About Exercise

Myth #1. Sit-ups will help you lose fat around your stomach.

When it comes to body fat, it comes off proportionately from your entire body. You cannot spot-reduce fat deposits. Sit-ups and other resistance exercises will, however, tone the muscles beneath the body fat.

A new study from Ball State University used a high-tech scanning device to measure fat on the bodies of 31 women before and after 6 months of cardiovascular and strength exercises. On average, women lost 31 percent of their upper body fat. There was a 12 percent loss in abdominal fat. Finally there was 6 percent more lean muscles in the thighs and legs.

Myth #2. Exercise turns fat into muscle.

One type of tissue can never turn into another type. Exercise requires energy, which your body provides by burning fat. At the same time, exercise improves existing muscle tone. Instead of weak, flabby muscles covered by a thick layer of fat, you'll have stronger muscles covered with a thin layer of fat.

Myth #3. People with high blood pressure shouldn't lift weights.

Most people who suffer from high blood pressure can benefit from weight training as long as the weight isn't excessive, they switch types of weights frequently and they breathe properly. That means exhaling during the workout or weight lifting, and inhaling during the resting phase. Never hold your breath when exercising or lifting weights. Always consult your doctor before beginning an exercise program, especially when you suffer from high blood pressure.
