Only modestly compared with free-weight squats. The back support reduces balance and trunk demand, even though some bracing is still required.
The calves support ankle control on the platform, but ordinary hack squats are secondary calf work unless the machine is used for a deliberate calf-raise variation.
Only modestly. The guided path emphasises knee and hip extension, while the hamstrings usually receive less direct tension than in hinges or curls.
Yes. Hack squats are one of the clearest machine-based options for progressively loading the quadriceps through a stable path.
Yes. Deep, progressively loaded hack squats can train the glutes, although machine design and foot placement strongly affect the hip demand.
They train the core to stabilise the trunk over a wide base, though the movement is still primarily a lower-body exercise.
The calves help stabilise the feet and ankles, but the wide stance does not turn the squat into a strong calf-building exercise.
The hamstrings contribute to hip control, yet sumo squats are still a secondary hamstring exercise rather than a substitute for hinges and curls.
Yes. The quads still extend the knees in a wide-stance squat, although an extremely wide stance can change the balance of work toward the hips.
