A Weighty Issue for Exercise Buffs
Dumbbells Are Smart
Want another reason to become friends with some dumbbells? A
Tufts University study, published in the August 1994 issue of the American
Journal of Clinical Nutrition, found that people ages 56 to 80 who
weight-trained three times a week increased their resting metabolic rate by 7%.
The participants gained three pounds of muscle and lost four pounds of fat
while increasing their daily caloric intake by 15%.
"Strength training should be part of every weight loss
program," Westcott says.
The American Heart Association recommends performing an aerobic
workout six days a week for 30 minutes and two to three weight training
sessions a week. But if you're like most Americans, you don't exercise because
you think you don't have time to press some pounds. Not true, say Westcott and
others in the field.
"Give me 10 to 15 minutes a day, two days a week and you
will see a difference," Westcott promises.
If you want to start a weight workout, Westcott suggests that
you first talk to your doctor and have a complete physical. Then, when you're
ready, you can begin with these basic exercises:
- A chest press or another pushing exercise.
- A rowing exercise or another type of pulling exercise.
- A major leg muscle exercise like a squat or leg press.
- A core body exercise for the midsection, like sit-ups or crunches.
Westcott suggests weight training every other day, with an
aerobic workout on the off days.
"In most studies, if we are doing 15 to 20 minutes of
strength training, we do 15 to 20 minutes of aerobics," he says. "You
don't have to do a lot to get fairly significant changes."
