"One of the reasons that subtle changes in variables such as heel elevation may not make as much of a difference to what you feel, or the end outcome (hypertrophy, strength) as you might predict is due to a very interesting feature of bi-articular muscles. This is known as Lombard’s Paradox (Lombard and Abbott 1907), a phenomenon whereby the knee extensors can contribute to hip extension, and the hip extensors can contribute to knee extension.

Rectus femoris, the bi-articular quadricep muscle, can act as a “pulley” that aids in knee extension as the glutes extend the hip. Therefore, even when we do have a greater moment at the knee, it doesn’t always result in less work in the glutes, since they can still contribute. Likewise, as the knees extend, they also pull on the hamstrings, whose tension can then assist with hip extension. Essentially, the bi-articular muscles function together in squat exercises, which can explain some of the indifference that you may “feel” when performing squat variations."
