assertion
Analysis v1
When you squat, your front thigh muscle can't work as hard because it's stretched across two joints at once.
Scientific Claim
Bi-articular muscles, such as the rectus femoris, exhibit reduced force production during compound movements that demand simultaneous hip and knee extension due to active insufficiency.
Original Statement
“During squats, the bi-articulate rectus femoris muscle cannot effectively contribute force because it would pull you into hip flexion and essentially pull you back down into the squat, even though its role doing leg extension would be beneficial.”
