VMO stands for vastus medialis obliquus. In layman’s terms, it is your inner quadricep muscles. This muscle has a lot to do with the tracking of the knee cap. As a result, strengthening your VMO will help to make your knees stronger, more resilient and may even help to offset existing pain.

In this article, I’m about to lay out the seven best exercises to strengthen your VMO.

Exercise #1: Lying Leg Lift

How to Do It:

  1. Lie on your back with both knees bent. Now straighten out your right leg, with the heel resting on the floor. Lock the knee on this leg.

  3. Without bending the knee, lift the extended leg directly up. The movement should all come from the hip. Bring the leg up until it is level with the opposite thigh.
  4. Slowly lower the leg to the floor.
  5. Do 2 sets of 10 reps on each leg.

Exercise #2: Ball Squeeze
