How many sets and reps of the belt squat should you do when you are new to the exercise?

Do 3 sets of 10 to 12 reps at a moderate load, since the belt setup removes spinal loading and lets you focus purely on leg volume. Rest 60 to 90 seconds between sets. Progress by adding a small amount of weight each week once you can hit full depth with an upright torso and flat heels on every rep.

What can replace the belt squat without a belt squat machine?

A dip belt looped through a loaded barbell or a suspended plate, straddled between two sturdy boxes, recreates the same hip-hung loading. A leg press or a goblet squat is a reasonable fallback that still spares the spine somewhat, though neither hangs the load from the hips the same way.

Who should use the belt squat, and when is a regular squat the better choice?

It builds quads and glutes with the spine and shoulders left out of the load, ideal for lifters managing back issues or stacking extra leg volume on top of heavy squats. It's a poor choice as a main strength lift for someone with full access to barbell squats, since it won't build the trunk bracing a back squat does.

Intermediate

Belt Squat

Hanging the resistance from a belt around the hips loads the legs directly while leaving the spine and shoulders completely out of it, so you can train the quads and glutes hard without axial fatigue. Because you stand on a raised platform and often hold handles for balance, it is a superb option for lifters managing back issues or adding leg volume on top of heavy squats. The upright torso and forward knee travel keep the quads working through a full range.

How to do it

1
Stand on the platform of a belt squat machine or straddle two boxes with a belt and hanging load.
2
Fasten the belt snugly around your hips and take the weight by standing tall.
3
Set your feet shoulder-width with the toes slightly turned out and grip the handles if available.
4
Brace the core and squat straight down, letting the knees travel forward over the toes.
5
Descend until the thighs reach at least parallel while keeping the torso upright.
6
Drive through the mid-foot to stand back up without leaning on the handles for the lift.

Tips

Use the handles only for balance; let the legs do the work rather than pulling yourself up with the arms.
Keep the torso tall to let the knees drift forward and load the quads through a deep range.
Set the belt on the hip bones, not the waist, so the load pulls down cleanly through the legs.

Variations

Common mistakes

The heels lift off the platform partway through the descent, shifting load onto the ankles and away from the quads and glutes the belt is meant to isolate.
The chain or strap is left with slack at the bottom of the rep, so the load jerks tight partway through the ascent instead of resisting the legs the whole way up.
Turning the toes out further than the knees can comfortably follow sends the knees tracking inward while the hanging load swings side to side instead of straight down.
The lower back rounds and the hips tuck under at the bottom since nothing on the back enforces spinal position the way a barbell squat does, and the hanging belt makes that rounding easy to miss.
