Primary: Quads

Secondary: Glutes Hamstrings

Movement: Compound

Tags: Balance / Stability Squat Unilateral

Type: Functional Fitness (Obstacle & Hybrid)

Equipment: Body Weight

Sports: Basketball Football Rugby Running Soccer Tennis Track and Field Volleyball

Target muscles

The quadriceps and gluteus maximus of the standing leg drive the entire lift. The hamstrings co-contract for knee stability. The trunk braces continuously. The hip flexors of the free leg hold the extended position. As bodyweight strength goes, the pistol squat is the apex.

How to perform

Setup

Stand on one leg with arms extended forward for balance. The opposite leg slightly raised in front. Trunk braced.

Execution

Bend the standing knee and sit back into a single-leg squat. Lower as far as you can — ideally hip below the knee. Drive through the heel to return to standing. Complete all reps on one side before switching.

Common mistakes

  • Heel lifting.
  • Knee diving inward.
  • Torso pitching forward.
  • Loss of balance.
  • Cutting depth.

Progressions and regressions

Regress to box pistols (sit to a target depth) or assisted pistols. To progress, add load (kettlebell or dumbbell at the chest), work for reps.

Programming notes

Apex single-leg lift. 3 sets of 3-5 per side, twice a week.
