[3] The first prototype is recognized to have been made under Gustav Zander, but labeled the machine as a form of “mechanotherapy” along with other machines that extended the knee and ankle. [3] The machine was made to target the quadriceps.

Bridging exercises are done with a flexed knee to lessen the stretch on the hamstring (a knee flexor) and focus the hip extension work on the gluteus maximus. In that same respect, the reduced knee flexion makes plantar flexion work comparable to a seated calf raise, due to the lessened stretch on the gastrocnemius (like the hamstring, also a knee flexor).
