1. A better range of motion (improved joint mobility and flexibility). To increase your range of motion, move a joint as far as it can go and then try to push a little farther. Do them gently.
2. Stronger muscles (through resistance training). This simple exercise can help ease the strain on your knees by strengthening your thigh muscles: Sit in a chair. Now lean forward and stand up by using only your thigh muscles (use your arms for balance only). Stand a moment, then sit back down, using only your thigh muscles.
3. Better endurance. Aerobic exercise — such as walking, swimming, and bicycling — strengthens your heart and lungs and thereby increases endurance and overall health. Avoid high-impact activities such as jogging.
4. Better balance. There are simple ways to work on balance. Stand with your weight on both feet. Then try lifting one foot while you balance on the other foot for 5 seconds. Repeat on the other side. Over time, work your way up to 30 seconds on each foot.
“Exercise should be regarded as tribute to the heart.” Gene Tunney
