Most people understand the effect of aerobic exercise and its role in weightreduction and cardiovascular fitness. Many do not understand the connection between weighttraining, weight gain, and aging.
After the age of 20, our bodies lose 1/3 to 1/2 pound of muscle tissue per year. Ofcourse, this results in strength reduction as we would expect.
However, it also slows our resting metabolic rate. This is the rate our bodies consumecalories when we are not working, even when we are sleeping.
The slowing of our metabolic rate translates into weight gain. Weight training, even twicea week, will help you maintain and even replace that lost muscle mass. Although weighttraining will produce extra strength in as little as six weeks, experts tell us to allow12 weeks for physical changes to be obvious.
Weight training twice a week also has another bonus. It helps combat osteoporosis. Asmuscles strengthen, so do the underlying bones.
It is true that the more we sit, the more we want to sit. If you are thinking you justdon’t have the energy to exercise at the end of a long work day, consider the fact thatexercise actually increases your energy. You feel like doing more, not less.
Decreased stress levels and better overall health and quality of life are additionalbenefits of exercise.
If you will consistently exercise (combination of aerobic exercise and weight training)for only 15 to 20 minutes per day for 12 weeks, you will be delighted at the feeling ofcontrol and power you feel with your own body. And as you replace muscle mass, you willsee your weight gradually come down.
