This 25-Minute Leg Workout Is Designed For Those With Knee Pain

Dr. Malek said it's important to keep the gastrocnemius — one of the major muscles that crosses the knee joint — strong and flexible, as it's one of the major push-off muscles.

• Stand tall and keep the knees straight.
• Lift from the heels by squeezing the calves.
• Be sure not to go too high that you end up just being on the toes. Maintain control, and lower.
• Perform 3 sets of 12 reps, with 30 seconds rest in-between.
