7. Stationary bike
Strengthens hamstrings and knee ligaments while increasing range of motion without impact.
Ensure that when your foot is at the bottom of your pedal stroke, your leg is almost straight, but the knee maintains a 15 degree angle. Your initial cycling goal should be 10 minutes a day at light resistance and add an extra minute each day until you reach your daily goal. A desk bike is a perfect solution for strengthening exercises.
