Loaded quads with zero spinal stress.
Track your knees over your toes, don't let them cave inward as you stand.
The V squat machine locks your back against an angled pad and sends the load through a fixed arc, so your quads get squat-level work while your spine gets a day off. The angled path keeps you more upright than a free squat, which biases the quads hard, with the glutes driving as you push out of the parallel-depth bottom. It earns its place as the volume tool for leg day, heavy enough to matter, stable enough to push to the edge without a spotter.
They are close cousins, both machine squats with back support. The V squat's arced path tends to feel more natural through the hips, while a hack squat runs on straight rails, try both and keep the one your knees prefer.
Shoulder-width and centred is the baseline. Lower on the platform bakes in more quad, higher shifts work toward the glutes, just keep your whole foot planted so your knees track over your toes.
It can carry your quad development, especially if back fatigue or mobility limits your free squatting. You lose the balance and bracing skill of the barbell, so keep free squatting if strength in that pattern is a goal.
