Pistol squat: how to do a single-leg squat and build up to your first rep

A pistol squat is a full squat on one leg while the other leg is held straight out in front of you. Reach your arms forward for balance, sit down until your hamstring meets your calf, keep your heel down, and stand back up on the same leg. If you cannot reach the bottom yet, squat to a box or hold a support and lower the height over time.

How to do the pistol squat

A pistol loads one leg with your whole bodyweight through a full range of motion, so it builds real leg strength with no equipment. It also asks for ankle and hip mobility and balance, and it shows quickly if one leg is weaker than the other.

Steps

  1. Stand on one foot with a box or bench just behind you, reach your arms straight forward, and lift the other leg slightly off the floor in front of you.
  2. Brace your stomach and start bending the standing knee and hip together, letting the knee travel forward over your toes.
  3. Lift the free leg higher as you descend so it stays clear of the floor, and keep your whole foot planted.
  4. Sit down under control until you touch the box lightly; once that is easy, lower the box until the back of your thigh meets your calf.
  5. Push the floor away through your midfoot and heel and stand up without letting the free leg drop or the knee cave in.

Cues

  • Arms long, chest over the knee
  • Whole foot on the floor
  • Slow down, strong up

Common mistakes

  • Heel lifting off the floor: put a small plate under the heel or squat to a box until your ankle mobility catches up.
  • Falling backward at the bottom: reach your arms farther forward or hold a light weight in front of you as a counterweight.
  • Dropping into the bottom and bouncing: lower in about three seconds and stop where you still control the descent.

Muscles the pistol squat works

The pistol squat mainly works the quads and glutes of the standing leg. The adductors and the small hip muscles keep the knee tracking over the foot, the calf and foot muscles handle balance, and the hip flexors and abs hold the free leg up in front of you.

Sets, reps and reps in reserve for the pistol squat

GoalSets × repsRIRRest
Learn the movement 3–4 × 3–6 per leg 2–3 90 s
Squat to a box or hold a doorframe; lower the box or use less help as reps get smooth.
Build strength 3–4 × 5–8 per leg 1–2 2 min
Once full reps are easy, hold a light dumbbell or kettlebell at your chest.
Build muscle 3 × 8–12 per leg 1–2 90 s
Use a slow three-second descent so the set lasts long enough without extra weight.

How to progress to your first pistol squat

Work backward from the full rep. First, squat on one leg down to a box or bench at knee height and stand up without rocking. Then lower the box a couple of inches at a time. In parallel, practice the bottom by holding a doorframe or post and sitting all the way down, using your hands only as much as you need.

If balance is the problem, hold a light plate or dumbbell straight out in front of you; the counterweight makes the bottom easier. If your heel lifts, put a small wedge under it. Log each version with the reps and RIR so you can see when it is time to remove a support.

Are pistol squats hard on your knees?

A pistol bends the knee fully under your bodyweight, so it is demanding, but a controlled pistol is not a knee-wrecker for healthy knees. The trouble spots are a fast drop into the bottom and the knee caving inward. Lower slowly, keep the knee over your toes, and stop above the depth that hurts. If deep knee bending is painful, a box pistol to a comfortable height or a split squat is a better choice.

Questions

Are pistol squats good to do?

Yes, if you can do them with control. They build single-leg strength, balance and mobility with no equipment, and they expose differences between your legs.

What muscles do pistol squats work?

Mainly the quads and glutes of the standing leg, with the adductors, calves and foot muscles stabilizing and the hip flexors and abs holding the free leg up.

Why can't I do a pistol squat?

Usually one of three things: ankle mobility (the heel lifts), balance (you fall backward), or strength out of the bottom. Box pistols, a counterweight and a heel wedge each fix one of those.

Is a pistol squat the same as a single-leg squat?

A pistol is one kind of single-leg squat: the free leg goes straight out in front and you go to full depth. Skater squats and box squats on one leg are other single-leg squats.

Do you need equipment for pistol squats?

No. A box, a doorframe or a light weight helps while you learn, but the full exercise needs only the floor.

Which squat is best for bad knees?

Squats that keep the range you can control without pain, like a box squat or a box pistol to a comfortable height, are usually easier on sensitive knees than deep, fast squats.
