Passage 3 You probably think you have to be big and buff to benefit from weight-lifting, but in reality,
you do not. You just need to learn how to weight train properly in order to get the results you want.
Everyone wants a perfect body. For a guy, the ideal image is broad shoulders, big pecs, and a six
pack. For a girl, it is a well-toned body. But looking good on the outside is not necessarily the same
as being healthy on the inside. To be healthy, you need to eat a good diet and get lots of exercise.
Weight-lifting can be part of an exercise program, but it is important to distinguish weight-lifting
facts from myths.
One myth about weight training is that you have to work out everyday. Muscle tissue needs at
least 48 hours to recover from hard exercise, so working the same muscle two days in a row is
over-training and provides no benefit. Arnold Schwarzenegger once said: “It is not how many hours
you put in, it is what you put in the hours.” It is not good to strain your muscles, but it is good to
work out hard. Forty-five minutes to an hour in the gym four to five times per week is enough for
young people. Your body actually gains strength and mass while you rest, so it is also important to
get plenty of sleep.
