Belt Squat

Move · Resistance Training · Movement, Typed Supps

Hanging the weight from your hips puts the load below your centre of mass, so nothing is pushing your chest towards the floor.

Stage by stage

Set-up (Load applied at the pelvis): The resistance vector passes below the trunk's centre of mass, so there is essentially no external trunk-flexion moment to resist.
During the set (Knee-dominant distribution): An upright torso shortens the hip-extension moment arm and lengthens the knee-extension one, biasing the quadriceps.
Immediately after (Erectors barely loaded): Trunk extensor work drops sharply, which is the intended feature and also what the exercise does not train.
Weeks later (Volume without axial fatigue): Weekly leg volume can be raised without accumulating spinal loading; the load ceiling becomes equipment rather than back strength.

Muscles trained

Primary: glutes, quads
Secondary: adductors, calves

Intensity

5 METs (Resistance (weight) training, squats , slow or explosive effort).

Time to effect

Weeks: Because the load never touches your spine, many lifters can push leg volume and effort noticeably harder in the first few weeks than a back-loaded squat allows, without the usual next-day back fatigue.
Months: Over 2 to 3 months, quad and glute size and strength climb, and it becomes a reliable way to keep training legs hard through periods when back-loaded squatting isn't an option.

Common myth

"A belt squat is basically a lighter, easier version of a real squat." In reality: Removing spinal loading doesn't mean removing leg loading. The legs still do the same work moving the same weight through the same range of motion; what disappears is the isometric demand on the lower back and core to stabilize an axial load, which is why the belt squat is often used to keep leg training heavy during a back injury rather than as a lesser substitute.
