The bent over rowis a fantastic exercise to strengthen and increase mass in the upper back and lats and reinforce hip hinge mechanics. As a result, its a much more physically demanding variation. At the deepest range in the squat, the quads will be working the hardest in order to extend the knees out of the bottom.
