Muscles worked
The belt squat trains your quads and glutes like a squat, with help from your inner thighs. The difference is where the load sits: it hangs from a belt around your hips instead of resting on your back. Your back and shoulders are spared from carrying it, and your trunk has less to do than with a bar. That makes it useful when your back is already tired from deadlifts, or when your shoulders struggle to hold a bar in place. The more upright you stand, the more of the work lands on your quads.
Common mistakes
- The belt slips. A belt that moves changes the line of pull in the middle of a set. Place it low around your hips and tighten it properly before you start.
- Standing out of line with the pull. Too far forward or back and the weight pulls you off balance. Position yourself so the chain or cable hangs straight down between your feet.
- Shallow reps. Without a bar on your back it feels easy to load up heavy, and many people then stop well short of their depth. Go down the same distance on every rep and choose the weight to match.
Variations and alternatives
- The back squat with the bar on your back also trains your trunk and balance, when your back is fresh.
- The hack squat is another machine with plenty of quad work, where you lean against a back pad.
- The leg press also takes load off your back, but you sit rather than stand.
Sets and reps
The belt squat works for both strength and muscle. For heavier work, 4 to 8 reps over 3 to 4 sets suits it, and 8 to 15 reps to build muscle. As your back is not the limiting factor, long sets work well too, as long as depth holds. Set-ups for different goals are described in the guide to sets and reps.
Designs vary a lot between gyms. A lever machine and a cable machine can feel completely different with the same number on the weights, so only compare yourself on the same machine. Add load only once every rep of every set reaches the same depth. That way, progressive overload rests on full reps rather than shallower ones.
