Belt Squat
The belt squat is a squat in which the load hangs from a belt around your hips instead of resting on your back. It works the quadriceps hardest, with the glutes and adductors assisting, and it is usually done on a dedicated belt-squat machine.
Also called: Belt Squat Machine, Hip Belt Squat, Machine Belt Squat, Pit Shark Squat · Equipment: machine · Pattern: squat
Step by step
- Step onto the platform and set your feet about shoulder-width apart with your toes turned out slightly, one foot either side of the chain or strap.
- Fasten the belt snugly around your hips so it sits low, below your waist, then clip it to the chain or strap. On blocks with a dip belt, the plates hang between your feet.
- Stand up to take the load, then release the machine's safety catch or lever. Rest your hands lightly on the handles or rail for balance.
- Stand tall with your chest up, take a breath and brace your trunk.
- Squat straight down between your feet, bending your hips and knees together. Let your knees travel forward over your toes while your torso stays close to upright.
- Go down until your thighs are at least parallel to the platform, as deep as you can while your low back stays neutral.
- Push the platform away through your whole foot and stand straight up, with your knees tracking in line with your toes.
- After the last rep, stand tall, re-engage the safety catch, then unclip the belt.
- Sit straight down between your feet
- Knees travel forward over your toes
- Chest tall, torso upright
- Spread the platform apart with your feet
- Press through your whole foot
- Hands on the handles for balance only

What goes wrong, and the fix
Cutting depth
Fix: Squat until your thighs are at least parallel, with your low back neutral.
Belt riding up to the waist
Fix: Seat the belt low on your hips and set the strap length before you load it.
Leaning the torso forward
Fix: Keep your chest tall and sit straight down between your feet.
Pulling on the handles
Fix: Rest your hands lightly on the handles for balance only.
Knees caving inwards
Fix: Push your knees out in line with your toes on the way down and up.
Heels lifting
Fix: Keep your whole foot flat and press through the midfoot and heel.
What the research says
Muscle growth · first choiceRehab & prehab · first choiceGeneral fitness · first choiceStrengthSport performanceEnduranceFat loss & conditioning
- Load by goal — Research comparing loads finds maximal strength favours heavier loads, while muscle growth is similar across a wide range of loads when sets are taken close to failure.
- Effort — Studies show sets that finish a few reps short of failure capture most of the growth benefit, and strength gains appear largely insensitive to how close to failure you train.
- Volume — Research links more weekly sets for a muscle to more growth, with diminishing returns. Around 10 or more hard sets a week has been associated with more growth than fewer than 5.
- Depth — In a barbell squat training study, full-depth squats grew the glutes and adductors more than half squats, while quadriceps growth was similar at both depths.
- Glute emphasis — An EMG study at a 5-rep max recorded less glute activity in the belt squat than the back squat, with similar quadriceps activity. Many lifters pair it with a hip hinge or hip thrust.
