Every physical activity you do requires a certain percentage of your maximum muscular strength. If you become stronger, then these activities require a lower percentage of your strength and require less effort to perform. While this is always important, it becomes even more important as you get older. Next, muscles are active tissues and burn calories. Fat tissue does not burn many calories.
Fat tissue s purpose is to store calories.
Thus, the more muscle and less fat you have, the more calories your body burns at rest and throughout the day. This will make it easier to control your body weight. Third, strength training not only makes your muscles stronger, it also makes your bones stronger. If you continue to strength train your muscles throughout your life you can increase your bone density. Thus, training your muscles can help reduce both muscle and skeletal injuries.
