Do you worry that working out could cause more knee damage or pain? As long as your doctor says it’s OK, the best thing you can do is to strengthen the muscles that support your knee and keep them flexible. Start slowly, and build up over time.
Warm Up First
You can ride a stationary bike for about 5 minutes, take a brisk 2-minute walk while pumping your arms, or do 15-20 wall push-ups followed by the same number of calf raises. Doing this will help you get more out of your workout, prepare you to stretch, and lower your risk of an injury.
1. Straight Leg Raises
If your knee’s not at its best, start with a simple strengthening exercise for your quadriceps, the muscles in the front of the thigh. This move puts little to no strain on the knee. Lie on your back on the floor or another flat surface. Bend one knee and place your foot flat on the floor. Keeping the other leg straight, raise it to the height of the opposite knee. Repeat 10-15 times for three sets.
