The pistol squat is the ultimate test of lower-body strength on one leg. You stand on a single leg, extend the other straight out in front of you, and squat all the way down until your hamstring meets your calf — then stand back up. No weights, no machine. Just you, balanced and strong on one leg. It looks like a circus trick, but it's a skill anyone can build with the right steps. Here's how to earn your first full pistol squat.

This is the lower-body entry in your bodyweight-skills set. It pairs with the pressing skill in our one-arm push-up guide, and slots neatly into our bodyweight plan for travel and hotels.

What is a pistol squat?

A pistol squat is a single-leg squat taken to full depth. You lower into a deep one-legged squat on your working leg while your other leg stays straight out in front of you, off the floor. Your arms usually reach forward to balance you. It's the hardest version of the bodyweight squat — instead of splitting the load across two legs, one leg does all the work through a full range of motion.

Why train the pistol squat?

Why chase such a hard exercise? Because it delivers a lot. The pistol squat builds serious lower-body strength with zero equipment — just a bit of floor. Because it's a single-leg movement, it exposes and fixes left-to-right imbalances that two-legged squats hide. It sharpens your balance and forces the ankle and hip mobility that keeps your knees healthy. And it travels anywhere — no rack, no weights, no gym. Few moves give you that much strength, mobility, and athleticism from one exercise.

What a pistol squat demands

Pistol squats require three things at once, which is what makes them so hard: strength, mobility, and balance. You need single-leg strength to lower and raise your full bodyweight on one leg. You need mobility — especially in your ankles and hips — to keep your heel down and stay upright in the deep position. And you need balance to hold it all together on one foot. Most people are missing at least one of these when they start. The good news: every one improves fast with practice and a smart progression.

Before you start: the prerequisites

Build a base first. You should be able to do a full, deep bodyweight squat with both feet flat and your chest up. You'll also need decent ankle mobility — if your heels pop up at the bottom of a normal squat, that's the first thing to fix. Finally, some single-leg strength helps, from moves like split squats and step-ups. Get comfortable there, and the pistol squat progression will go much faster.

The pistol squat progression

Work through these stages in order. Move on only when the current one feels solid.

  • Assisted pistol. Hold a pole, doorframe, or suspension trainer and lower into a one-legged squat, using your hands for just enough support. Let your legs do more of the work over time.
  • Box pistol. Stand on one leg in front of a box or chair. Sit back and down until you tap it, then drive up on the same leg. Start with a high box and lower it as you get stronger.
  • Heel-elevated pistol. Put a small plate or wedge under your heel. This reduces how much ankle mobility you need, so you can train the full movement while your mobility catches up.
  • Negatives. Lower slowly into a full pistol on one leg, then use both legs or your hands to stand back up. You're stronger lowering than rising, so this builds the bottom-end strength you need.
  • Full pistol squat. One leg, full depth, no help, standing straight back up. That's the goal.

Don't ignore mobility

Since pistol squats require real ankle and hip mobility, train it directly. For ankles, do slow, deep lunge stretches where you drive your knee forward over your toes, keeping your heel planted. For hips, work deep squat holds and gentle hip openers. A few minutes of this strength and mobility work before each session pays off fast. If your heel keeps lifting at the bottom, mobility — not strength — is usually the thing holding you back.

How to do a pistol squat

  • Stand on one leg with the other extended straight in front of you, just off the floor.
  • Reach your arms forward as a counterbalance, and keep your chest up.
  • Push your hips back and bend your standing knee, lowering under control. Keep your heel flat the whole way.
  • Go all the way down until the back of your thigh nearly touches your calf, keeping your extended leg off the ground.
  • Drive through your heel and stand back up in one controlled motion, without letting your knee cave inward.

Move slowly and stay in control. Train your weaker leg first, then match it with your stronger side.

Every pistol squat is a balance test as much as a strength test. Slow, controlled reps win — an uncontrolled drop is just a fall you got away with.

Common mistakes

  • Heel lifting. If your heel rises, you lose power and balance. Work your ankle mobility and keep the heel glued down.
  • Knee caving in. Keep your knee tracking over your foot, not collapsing inward.
  • Rounding your back. Keep your chest up and spine long, especially at the bottom.
  • Rushing. A fast pistol becomes an uncontrolled drop. Own every inch, up and down.

How to train it

Practice pistol squats or your current progression two or three times a week. Do 2 to 3 sets per leg, always starting with your weaker side and matching the reps on the other. Keep a rep or two in reserve — quality beats grinding out sloppy ones. Add a rep or lower the box over time, and let your strength and balance climb together.

The pistol squat is Connfi training in one move: no equipment, no ego, just strength, balance, and the patience to climb the progression. Warm up first with a few warm-up sets, and stick with it — one day you'll stand tall out of a full single-leg squat.

A quick note: the pistol squat is demanding on the knees and ankles. Build up gradually, and back off or check with a qualified coach if you feel joint pain.
