Belt Squat

The belt squat attaches the load — a stack of plates or a weight pin on a belt-squat machine — to the waist via a strap, allowing the lifter to squat without a bar on the back or in the front rack. The hands are free to hold onto handles or a support bar for balance. Without axial loading, the spinal erectors and lower back get a break while the quads, glutes, and hamstrings do the work.

The belt squat is the primary squat variation in many of Louie Simmons's later Westside templates and appears in high-volume hypertrophy programs that run daily lower-body work. Its value is that it lets you program additional squat volume without adding spinal compression fatigue. A lifter running a heavy squat day and a heavy deadlift day in the same week can add a belt squat volume day without stacking axial load on top of those sessions.

Loading potential is substantial — the belt can carry plates well past what the lifter's axial system would tolerate. Most lifters belt squat their back squat working weight for 2-3x more reps because the back stops being the limiter. This makes belt squats ideal for rep ranges (8-15) that would be destructive if run with a bar.

Machines vary widely. Dedicated belt squat machines use a pivoting arm and selectorized stack; cheaper setups use a dip belt and a platform over an open trap or plate-loaded device. The movement pattern is the same regardless: hinge at the hips, break at the knees, descend to full depth, drive up. In LiftProof, track belt squats as their own exercise — the load is not comparable to a back squat and merging the histories obscures both.

• Hips back first, then knees — the same hinge pattern as a regular squat
• Full depth is easier without a bar — use it. Below-parallel squats are the norm here
• Grip the handles loosely — they are for balance, not to pull yourself up
• Drive the feet through the floor — belt squats reward quad and glute drive, not back extension
• Keep the torso upright — the belt does not fight you, so leaning forward adds no mechanical advantage

• Treating it like a leg press — the belt squat is still a squat pattern and should not turn into a seated knee extension
• Loading too light — the lack of spinal load means the quads and glutes can handle much more than lifters expect
• Short-changing depth — going to parallel by habit when you could easily hit ass-to-grass
• Using it as a back-pain workaround rather than a programming tool — if your back hurts, address the cause rather than just removing the bar
