V Squat.

Your back gets a vote.

Free squats often stop at something other than the legs: an old lower back, a wrist that cannot take the grip, or a neck that does not want a hundred kilos resting on it. The shoulder and back pad spreads the load over the whole back, and the V-shaped path keeps the knee at a fixed angle through the whole squat, so you get the same work in the quads and glutes without something else having to approve it first. 174 kg of dead weight keeps the frame still under heavy sets, and the machine takes 1760 × 1445 mm of floor with 1620 mm height. Olympic plates (Ø50 mm). The legs decide when the set is over.
