Box Squat with Chains
Muscles worked
Instructions
- 1Begin in a power rack with a box at the appropriate height behind you. Typically, you would aim for a box height that brings you to a parallel squat, but you can train higher or lower if desired.
- 2To set up the chains, begin by looping the leader chain over the sleeves of the bar. The heavy chain should be attached using a snap hook. Adjust the length of the lead chain so that a few links are still on the floor at the top of the movement.
- 3Begin by stepping under the bar and placing it across the back of the shoulders. Squeeze your shoulder blades together and rotate your elbows forward, attempting to bend the bar across your shoulders. Remove the bar from the rack, creating a tight arch in your lower back, and step back into position. Place your feet wider for more emphasis on the back, glutes, adductors, and hamstrings, or closer together for more quad development. Keep your head facing forward.
- 4With your back, shoulders, and core tight, push your knees and butt out and you begin your descent. Sit back with your hips until you are seated on the box. Ideally, your shins should be perpendicular to the ground. Pause when you reach the box, and relax the hip flexors. Never bounce off of a box.
- 5Keeping the weight on your heels and pushing your feet and knees out, drive upward off of the box as you lead the movement with your head. Continue upward, maintaining tightness head to toe.

About Box Squat with Chains
The chain box squat uses the same box-pause principle as the banded version, but with chains that progressively rest on the floor as you descend, reducing effective load at the bottom and increasing it near the top. This variable resistance keeps the hardest point of the lift safer while forcing maximal acceleration on the way up. It's a classic powerlifting tool for building power out of the bottom of the squat without overloading the lower back in the deepest position. The box pause also reinforces a controlled backward hip pattern.
