Pictured above is the most influential of the quadriceps, the rectus femoris. The leg on the right has the rectus femoris labeled. This is the only quadriceps that acts on the 2 largest joints in your body - the hip AND the knee. If this muscle goes dysfunctional with too many muscular knots, then all movements involving either of these two joints will be compromised. If you only have time for one SMR exercise, DO SMR FOR THE RECTUS FEMORIS! (It is that important.)
The leg on the left has all the muscles that cross your thigh in the region of the rectus femoris. All of the muscles in the left leg are see-through so that you can appreciate the location and size of each muscle relative to the others.
