Aerobic exercise, which speeds up your heart rate and breathing, is important for many body functions. It gives your heart and lungs a workout and increases endurance.
As we age, we lose muscle mass. Strength training builds it back. Strengthening your muscles not only makes you stronger, but also stimulates bone growth, lowers blood sugar, assists with weight control, improves balance and posture, and reduces stress and pain in the lower back and joints.
Stretching helps maintain flexibility. We often overlook that in youth, when our muscles are healthier. But aging leads to a loss of flexibility in the muscles and tendons. Muscles shorten and don't function properly. That increases the risk for muscle cramps and pain, muscle damage, strains, joint pain, and falling, and it also makes it tough to get through daily activities, such as bending down to tie your shoes.
Improving your balance makes you feel steadier on your feet and helps prevent falls. It's especially important as we get older, when the systems that help us maintain balanceβour vision, our inner ear, and our leg muscles and jointsβtend to break down.
