The VMO – vastus medialis oblique - is often better known as your “teardrop muscle”. It’s located on the medial side (inside) of the knee and is part of the quadriceps group. The sad truth is, most people have issues in their big lifts like squats, deadlifts, and split stance work due to inefficiencies in this little muscle.
The VMO, as small as it is, is a big stabilizer to the knee joint. If it’s not firing, you’ll notice issues with weakness at the bottom of your squat, incomplete depth, and wobbling. On top of this, you’ll likely be experiencing chronic knee pain in any given place surrounding the kneecap.
Try this workout to kick-start the VMO into action:
Remember to push through the balls of the feet the entire time, and don’t put too much pressure on the heel. Doing so will encourage the quadriceps(VMO especially) to fire more exclusively.
Perform 3 sets of 15 reps per leg, and keep a slow tempo for all reps.
Before adding weight, look to increase your range of motion by using a higher box. Remember to keep good technique. As the box gets higher, work to slow your descent to the floor – don’t just “drop” or “fall” downwards!
Perform 3 sets of 15 step ups per leg.
To progress this movement, use a lower box. Remember to keep the tension on the quads the entire time, and press through the ball of the foot.
Work for 12 reps per leg and perform 3 sets.
One More Thing
It’s important to know that when one muscle isn’t doing its job, another muscle likely is. In the case of a sleeping VMO, the muscles on the lateral side of the leg are often tight and overused to correspond. That being said, it’s encouraged to foam roll the IT band and outer thigh muscles, so they can be relaxed and forfeit some of the stress they’re undergoing during exercise when left unattended.
If you’re a guy struggling with the performance of your big lifts, taking a look at your VMO can be just what the doctor ordered to bust through a plateau. You’ll be glad you did – and your knees will thank you too!
