As this is the third episode of the quadriceps group and you know that they are a powerful group of muscles on the front of the thigh. And that together, as a group, they are responsible for knee flexion.

We’ve covered two of the four muscles of the quadriceps group in the last two episodes and today we’re truly diving deep (get it that’s a muscle joke!) to the Vastus Intermedius which lies under the Rectus Femoris and between the Vastus Lateralis and Vastus Medialis. And, we’ll finish up talking about the quads with the Vastus Medialis.
