Again, just to put some impotence behind my reckoning.
All the muscles in the legs are used to generate the biggest power output possible & its actually the glutes that turn on the power, the "push", not the quads. Although I have to admit, I would have thought the hamstrings played a similar role in the pedal stroke just as much as the quadriceps play.
Stepups and lunges generated significantly more muscle activation in the gluteus medius than squats. The horizontal and vertical leg presses generated the least amount of activity. The Hamstrings; Quadruped hip extensions, step-ups, lunges and four-way hip extensions showed significantly more EMG activity than squats. The horizontal and vertical leg presses ranked lowest in EMG activity.
