Descending to full depth on one leg while the other hovers out front is as much a mobility exam as a strength feat - ankle range and hip flexor strength fail people more often than the quads do. Build up through box pistols and reps with the heel raised on a small plate; one clean rep per side is a genuine milestone.
How to do the Pistol Squat
- Stand with your feet shoulder-width apart and arms extended in front of you.
- Lift your right foot off the ground and extend it forward.
- Slowly lower your body down by bending your left knee and pushing your hips back.
- Keep your chest up and your back straight as you lower yourself down.
- Lower until your left thigh is parallel to the ground, or as low as you can comfortably go.
- Pause for a moment at the bottom, then push through your left heel to return to the starting position.
- Repeat for the desired number of repetitions, then switch legs.
Tip: Screw the feet into the floor and spread it apart to keep the knees out and the arch of the foot from collapsing.
Muscles worked
Primary
Glutes · Legs
The glutes extend the hip on the way up and take more of the load the deeper you go and the wider your stance.
Secondary
- Quads — The quads extend the knee and drive you out of the bottom, and front squats and close stance variations put more on them.
- Hamstrings
- Calves
Common mistakes
- Knees caving inward — push the knees out over the toes on the way up, especially out of the bottom where they most want to collapse.
- Hips shooting up first — if the hips rise faster than the chest on the way up, you turn the squat into a good morning; drive the chest and hips up together.
- Cutting the depth — get the hip crease below the top of the knee on every rep unless mobility genuinely stops you, in which case work on it.
- Losing the brace — take a big breath into the belly before each rep and hold it through the sticking point, then exhale on the way up.
Where it fits in a workout
Squats go first in a lower body session when you are freshest. Follow them with Romanian deadlifts or leg press, or superset lighter sets with pull-ups to use the same rack.
How many sets, how heavy and how hard: see what the ACSM position stands support.
