Single-leg training builds strength you actually use: getting off the floor, climbing stairs, carrying a kid on one hip, catching your balance when you step off a curb wrong. That is the kind of strength I care about most as a physical therapist, and it is the kind a barbell back squat never fully covers.
Training one leg at a time exposes what working both legs together hides. Strength gaps, balance gaps, the side that quietly does less of the work. Close those, and everything from sport to ordinary daily movement gets steadier.
I’ll walk you through the single-leg moves we lean on most, how to scale each one, and a short guided session you can follow along with right now.
Single-Leg Training Is Strength You Can Use
Single-leg work earns its place for a simple reason. It builds stability, strength, and coordination in the exact positions you move through every day: walking, climbing, twisting, carrying a load on one side.
It also finds the weak points that two-legged training hides. When both legs share the work, your stronger side quietly covers for the weaker one. Stand on one leg and that cover disappears. You train the gap directly, which is how you steady wobbly knees and hips and lower your injury risk over time.
There are dozens of ways to train one leg at a time. Rather than drown you in variations, I want to focus on the handful that consistently deliver for our clients.
Start With This Guided Session
Before we break down each move, here is Ryan walking you through a short three-move session you can do today. It opens with a quick test. Stand on one leg, reach your free foot slowly behind and across your body, tap the floor out to the far side, and come back to center without setting it down. That wobble you feel is your hip working to control rotation on one leg, and it is the exact quality most leg training skips.
The session trains three directions a normal squat leaves out: loading one leg out to the side, dropping into a rotation, and driving up out of the turn. Follow along, then run the test again at the end. The wobble usually settles, which means your hips are already getting better at controlling that turn.
You can start with those three on their own today. They are the core of what we build in Integral Strength, on top of the foundation you get in Elements.
Pistol Squats and Shrimp Squats
These two are our favorite single-leg strength builders. They look impressive, but the point is not the photo op. It is what you gain from practicing them: strength through a full range of motion, joint control under load, and mobility that holds up when you actually move.
It does not matter whether you are working toward your first rep or refining the bottom position. The practice is where the strength comes from.
Pistol Squats
The pistol loads one leg with your weight back over the heel. It leans on the glutes and asks for hip flexor mobility and balance at the bottom.
Two things that speed up your progress:
- Start from the bottom. Practicing from the lowest position you can hold builds control faster than grinding down from the top.
- Train the shift. The hard part is not standing up, it is the transition out of the bottom.

Shrimp Squats
The shrimp keeps your weight over the midfoot, more quad-dominant, and it is the friendlier place to start because it scales more cleanly than the pistol.
- Better for beginners. It is easier to modify rep to rep.
- Knees past toes is fine here. It is part of building knee strength, as long as you work into it with control.

Front and Back Scales
Scales are the overlooked one. They do not look hard, and then five minutes in you find muscles and balance reactions you did not know you were missing.
They build hip and foot stability, active flexibility, and precise control. More useful than that, they show you exactly where your movement is sloppy, which is the first step to cleaning it up.
- Start with the front scale. Lift one leg forward, posture tall, standing hip stable.
- Then the back scale. Lift the leg behind you, hips square.
- Balance is the whole package. Strength, awareness, and control working together, not just staying upright.

Peacock Squats
The peacock is the rotation piece, and you saw it in the session above. You load one leg, pull the other across so your hips twist, then squat down into that rotated position with your knee tracking past your standing knee.
That is a position almost nobody trains: building strength while the body rotates. It shows up the second life stops moving in a straight line. Dodging something on a run, reaching sideways in the kitchen, pivoting in a pickup game. Your hip controls that rotation on one leg, and when it cannot, you lose your footing.
- Start small. Even a slight shift of the back leg changes how hard your hip has to work.
- Feel the glute fire as your body resists the rotation. That is the point of the move.
Cross the foot further and sit lower as it gets easier.
You Do Not Need to Master Any of These First
It is natural to want to perfect one move before adding another. We are big believers in practicing the basics, but that does not mean hammering three exercises forever and never trying anything else.
So no, you do not need a full pistol before you try scales or peacock squats. You do not have to earn variety. Each variation teaches your body something different, and together they build a more adaptable, responsive lower body faster than any single move would on its own.
Once you have the basic shapes, start mixing them:
- Flow from a shrimp into a scale.
- Add a peacock rotation at the end of a squat.
- Pick variations based on how your body feels that day.
Out in the world you move in every direction at once. Train that way.
