Prisoner Squat

Prisoner Squat Exercise Description

The Prisoner Squat is a bodyweight squat performed with the hands placed lightly behind the head. It primarily strengthens the quadriceps and gluteus maximus, with the adductors, hamstrings, and calves assisting, while the core and spinal erectors stabilize the torso. The arm position encourages an upright torso, scapular retraction, and consistent bracing without using equipment. Depth is individualized—descend only as far as you can while keeping heels grounded, knees tracking over the feet, and a neutral spine. Allow the knees to travel forward as needed to keep balance over the midfoot; focus on knee alignment rather than a fixed rule about the toes. Emphasize controlled hip and knee flexion on the way down and coordinated extension to stand, avoiding bouncing or collapsing at the bottom.

How To Do The Prisoner Squat Exercise

‘- Stand with feet about shoulder-width, toes turned slightly out based on comfort.
– Lightly place hands behind your head; draw shoulder blades down and back, ribs stacked over the pelvis.
– Set a tall posture with a neutral spine and a soft chin tuck; eyes forward.
– Create a tripod foot: big toe, little toe, and heel evenly pressed into the floor.
– Inhale and brace the trunk 360 degrees.
– Begin the descent by bending hips and knees together, sitting between your heels.
– Keep knees tracking in line with the second/third toes; let them move forward as needed while heels stay down.
– Maintain an upright torso without arching the lower back.
– Lower to a depth you can control while keeping spine neutral and foot pressure balanced.
– Pause briefly, then drive through the midfoot and heel to stand, extending hips and knees together.
– Finish tall with glutes lightly squeezed, elbows wide, and head neutral—no rib flare or neck craning.

Prisoner Squat Tips

‘- Lightly place your hands behind your head and keep elbows wide to encourage an upright torso.
– Draw your shoulder blades down and back with ribs stacked over the pelvis to set your torso position.
– Use a soft chin tuck with eyes forward to help maintain a neutral spine.
– Create a tripod foot by pressing big toe, little toe, and heel evenly into the floor.
– Inhale and brace your trunk 360 degrees before you begin the descent.
– Bend hips and knees together and “sit between your heels” to start the squat.
– Let your knees move forward as needed while keeping heels down and pressure over the midfoot.
– Keep knees tracking in line with your second/third toes, focusing on alignment.
– Maintain an upright torso without arching your lower back throughout the movement.
– Lower only to the depth you can control with a neutral spine and balanced foot pressure, then drive through midfoot and heel to stand, extending hips and knees together.

Prisoner Squat Beginner Introduction

In the Prisoner Squat, bodyweight alone challenges the legs and trunk while the arms rest gently behind the head. This arm position encourages an open chest, shoulders drawn slightly back, and a tall, steady posture without relying on equipment. The movement mainly targets the quads and glutes, with help from the inner thighs, hamstrings, and calves, while the abs and back muscles work to keep the torso steady from start to finish.

This squat centers on smooth, controlled bending and straightening of the hips and knees. The body lowers between the feet only to a level that can be managed without the heels lifting or the back losing its natural curves. Pressure stays shared through the whole foot, with the knees staying in line with the feet instead of collapsing inward or drifting out wildly. As the body returns to standing, the legs extend together and the trunk stays organized, finishing in an upright, stable stance with the head, ribs, and hips neatly stacked.
