Resistance exercise lowers your blood pressure, improves balance, increases your metabolism, and, of course, strenghtens your muscles, bones and ligaments. It is important to note that resistance exercise is also very important for postmenopausal women. Lifting weights increases bone density. As we age we tend to lose our sense of balance and fall more often. Keeping the bones and muscles strong helps us maintain our balance, fall less often and resist bone fracture if we do fall.
Aerobic exercise is also important.
This could be as simple as walking. Keeping the cardio-vascular system in good condition helps us maintain our overall health. Walking for thirty mintues, three times a week can be very helpful. If this is too strenuous, try shorter distances at first. Walking every day is a goal you may want to consider.
