Load your legs hard with zero spine compression.
Stay upright and let the belt pull straight down. Don't lean on the handles to cheat.
The Pit Shark loads a squat through a belt around your hips, so your quads and glutes get hammered while your spine carries none of the weight, no bar on your back and nothing to hold up. That makes it gold for training legs hard around back trouble, or for stacking leg volume after heavy barbell work when your trunk is fried. The handles are there for balance only, the belt does the loading.
Anyone who wants big leg training without spinal loading, lifters managing back issues, and anyone adding quad volume late in a session. They also help when shoulder or wrist problems make racking a bar miserable.
Only to balance. If you are hauling yourself up with your arms the rep does not count, so lighten the stack and let your legs do all the standing.
Parallel or below. Because the belt pulls straight down and your torso stays upright, most people find depth easier here than under a bar, so take advantage of it.
