Single-leg squat (pistol) with a kettlebell in the rack — extreme unilateral lower-body strength.
Level: Elite
Primary: Quads
Secondary: Glutes Hamstrings
Movement: Compound
Tags: Balance / Stability Squat Unilateral
Type: Functional Fitness (Obstacle & Hybrid) Strength (Weight Lifting)
Equipment: Kettlebell
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. The trunk braces continuously against the asymmetric load. The hip flexors of the free leg hold the extended position. The shoulder of the racked side stabilizes the bell.
How to perform
Setup
Stand on one leg holding a kettlebell in the rack position on the same side as the standing leg (or opposite, depending on preference). The opposite leg held in front. Trunk braced.
Execution
Lower into a single-leg squat by pushing the hips back and bending the standing knee — the torso stays upright. Press back up to standing. Repeat.
Common mistakes
- Letting the heel lift.
- Knee diving inward.
- Torso pitching forward.
- Going too heavy before the bodyweight pistol is dialed.
- Loss of balance.
Progressions and regressions
Regress to box pistols (sit to a target depth) and bodyweight pistols. To progress, increase load or work for reps.
Programming notes
Apex single-leg lift. 3 sets of 3-5 per side, twice a week.
