SquatBWBox

Single-leg squat performed down to a box/bench, allowing controlled depth progression toward the full pistol squat without full unassisted range of motion.

Demo: Exercise Tutorial

Sets

3

Reps

5-8 per side

Rest

1:15

Contraindications

High single-leg knee flexion demand as box height decreases — progress gradually.

Setup

Stand on one leg in front of a box/bench, free leg extended forward.

Execution

  1. 1Extend the free leg forward, off the ground
  2. 2Lower under control until lightly touching the box
  3. 3Do not relax fully onto the box
  4. 4Drive back up to standing through the working leg
  5. 5Maintain balance throughout

Key cues

  • Sit back onto the box, stay controlled
  • Extended leg stays elevated
  • Chest up throughout
  • Push through the whole foot
  • Don't rest fully on the box

Common faults

  • Relaxing fully onto the box
  • Extended leg dropping to the ground
  • Losing balance sideways
  • Box too low for current strength level
  • Rushing the ascent

Tweaks

  • Lower the box height progressively over time
  • Add slight weight held in front for counterbalance
  • Combine with ankle mobility drills between sets

Regressions

Assisted Pistol Squat (TRX)

Progressions

Pistol Squat - Full

Muscles

Primary: Quadriceps, Gluteus Maximus

Secondary: Hip Flexors, Core

Notes

A standard progressive-overload method for the pistol squat — gradually lower the box over weeks/months.
