The split squat is the most effective lower-body exercise in the X3 system, and Dr. Jaquish recommends switching from the front squat to the split squat after Week 4 of the 12-Week Program.

The reason: when you train one leg at a time, your heart, lungs, and body's full resources focus entirely on a single quad and glute — driving that muscle to complete exhaustion before switching sides. Human biomechanics are built for single-leg movement, and the growth response reflects it. The core stabilization involved in the split squat also triggers a significant release of growth hormone, which accelerates fat loss — amplified further by variable resistance.

The Squat Belt makes this possible at full intensity. Bands attach at the hips instead of loading across the deltoids, freeing you to double bands for greater resistance and achieving a full range of motion — knee nearly touching the ground — before switching legs.

Sizing:

Size is based on hip circumference, not waist size. The belt sits across the hips and rear — a waist measurement will not give you the right size.

To measure: wrap a flexible tape measure around the widest part of your hips and rear, keeping it parallel to the floor.

If you are 6' or taller, consider sizing up to ensure full range of motion.\
