Before the first rep
How to set up
- 01
Learn the machine. Find how your machine starts and parks the load: most have a lever arm or carriage that rests on stops, and a handle or lever to lift it off and set it back. Set any adjustable stops just below the bottom of your squat.
- 02
Belt on. Fasten the belt snug around your hips, low on the pelvis rather than at your waist, with the attachment point in front. It should not slide up your belly when you squat.
- 03
Clip in. Stand on the platform and clip the chain or strap to the belt. Adjust the length so you can stand tall with the load lifted just clear of its rest, and still reach full depth before it touches down.
- 04
Stance. Feet about shoulder width or a little wider, toes turned out roughly 15 to 30 degrees, with the strap hanging straight down between your feet. Weight spread across the whole foot.
- 05
Hands. Hold the front handles or rail lightly for balance. Your arms steady you; your legs move the weight.
Step by step
How to do the belt squat
- 01
Take the load. Stand up tall to lift the weight off its stops, using the machine's start handle or lever if it has one. Settle your feet before the first rep.
- 02
Brace. Take a breath into your belly and sides and tighten your trunk. Hold it through the way down.
- 03
Descend. Break at the hips and knees together and sit straight down between your heels, knees tracking in line with your toes and torso upright.
- 04
Reach depth. Go until your thighs are about parallel to the floor or a little below, as deep as you can while your lower back stays neutral and your heels stay down.
- 05
Drive up. Push your whole foot into the platform and stand straight up, hips and chest rising together, until your hips and knees are straight. Breathe out at the top and re-brace.
- 06
Park the load. After the last rep, stand tall and set the weight back onto its stops with the start handle or lever, or squat down until it rests on them, before you unclip.

Fix these first
Common mistakes
Belt riding up to the waist
Fasten it low and snug on your hips. A high belt pulls you forward and makes the load feel like it is folding you in half.
Pulling yourself down or up with the handles
Hold the handles only for balance. If you need your arms to finish a rep, the set is over.
Knees caving in on the way up
Push your knees out in line with your toes for the whole rep. If they keep caving, lighten the load.
Short reps with heavy plates
Squat to about parallel every rep. Lower the weight until you can reach the same depth on the last rep as the first.
Heels lifting or weight on the toes
Keep your weight over mid-foot and the strap hanging straight down. If you drift forward, shift your feet so the pull stays vertical.
Rounding the lower back at the bottom
Only go as deep as you can with a neutral lower back. A wider stance with toes turned out a bit more often helps.
Stay safe
Learn how your machine catches the load before you put weight on it: most belt squat machines have a lever arm or carriage that rests on stops, and some let you set those stops just below your deepest safe point. To end a set you cannot finish, lower under control until the weight settles onto the stops, then unclip; never pull yourself up with your arms. If your machine has no adjustable stops, or you are using a dip belt between two boxes, finish sets a rep or two short of failure. Stop if you feel sharp pain in your knees, hips or back, or pain that runs down a leg, and get it checked by a qualified professional before loading up again.
Programming
Sets, reps and how much weight
| Goal | Sets | Reps | Load | Rest |
|---|---|---|---|---|
| Strength | 3 to 5 | 4 to 6 | 80–87% 1RM | 2 to 3 min |
| Muscle | 3 to 4 | 8 to 15 | 65–78% 1RM | 1.5 to 2.5 min |
| Endurance | 2 to 3 | 15 to 20 | 50–62% 1RM | 1 to 1.5 min |
Plan your next session
Put in a recent set. You get working weights for your goal, a warm-up and the plates to load.
Estimated 1RM 216 lb
Muscle sets
140–168lb
3 to 4 sets of 8 to 15 reps, 1.5 to 2.5 min rest. The range most people use it for. Take sets close to failure only with the stops set just below your depth.
Estimates use the Epley formula and work best from sets of 3 to 8 reps. Treat them as a starting point and adjust by how the first working set moves.
Questions
Belt Squat questions
What muscles does the belt squat work?
Mainly the quads and glutes, with the adductors helping out of the bottom and the hamstrings assisting a little. Your calves and abs keep you balanced, while your back and shoulders carry almost none of the load.
Belt squat vs back squat: which is better?
Neither is better for everyone. The back squat trains your trunk and upper back along with your legs and is the standard strength lift; the belt squat trains the legs with little load on your spine, so it is useful when your back or shoulders need a break or as extra leg volume after squatting.
How do you use a belt squat machine?
Fasten the belt low on your hips, stand on the platform and clip the chain or strap to the belt, then stand up to lift the load off its stops with the start handle or lever. Squat to about parallel with your torso upright, and after the last rep set the weight back on the stops before you unclip.
Is the belt squat good if you have back pain?
It often suits people whose backs do not tolerate a bar, because the load hangs from your hips rather than pressing down on your spine. You still need to keep your lower back neutral at the bottom, and if squatting of any kind hurts, get it checked before training through it.
Can you do a belt squat without a machine?
Yes. Hang plates or a kettlebell from a dip belt and stand on two sturdy boxes or benches so the weight can travel between them. It works well for moderate loads, but the weight swings more and there are no stops, so keep sets a rep or two short of failure.
How many sets and reps of belt squats should I do?
For muscle, 3 to 4 sets of 8 to 15 reps taken close to failure is a common range. For strength, 3 to 5 sets of 4 to 6 heavier reps, with full depth on every rep.
