The split squat is single-leg training's front door: feet split front and back, hips dropping straight down between them, one leg doing most of the work while the other spots. It is where the program starts building the leg-at-a-time strength that stairs, trails and every North Shore pastime actually run on.
The early wobble is not a flaw to apologize for — it is the exercise. Balance is being trained alongside strength, and it stabilizes within a couple of weeks of honest practice.
What it trains
Quads and glutes of the front leg with real balance demand, plus a stretch through the rear hip that desk-bound flexors quietly need. As the single-leg entry point it also calibrates left-right differences — most people find one, and finding it is the point.
Setup
- From standing, one long step back — feet end hip-width apart for balance, not on a tightrope.
- Front foot flat and rooted; rear heel up, rear leg soft — it is a kickstand, not a worker.
- Torso tall, hands free or dumbbells hung at the sides.
- Lower straight down until the rear knee approaches the floor, then drive through the front heel.
The cues we use
- Down, not forward — elevator, not escalator
- Front heel does the work
- Tall chest over level hips
Common faults, and the fixes
| Fault | Why it happens | The fix |
|---|---|---|
| Torso pitching over the front knee | The escalator error — travelling forward instead of down, usually a stance too short | Lengthen the split and cue the elevator descent; the rear knee should aim at the floor beneath the hips |
| Front knee wobbling side to side | New balance demand meeting untrained hip stabilizers | Slow the tempo, lighten or drop the load, fingertip support on a rack until the wobble narrows — it will |
| Rear leg over-working | Weight split between legs, defeating the single-leg purpose | Cue ninety percent of bodyweight into the front foot; the rear toe could nearly lift |
The ladder
Easier: Supported split squat — Fingertips on a rack upright or wall — removes the balance tax while the strength pattern builds
Harder: Rear-foot-elevated split squat — When flat-ground split squats with meaningful dumbbells finish strong — elevating the rear foot concentrates everything on the front leg
How it is loaded here
Bodyweight first until the wobble settles, then dumbbells at the sides climbing on the usual finishes-strong rule. Single-leg loads flatter your rack: the same dumbbells that plateaued your goblet squat are heavy again when one leg carries them — much of why this family extends dumbbell training so far.
When we swap it
- cranky knees: Shorten the range (higher bottom position), slow the descent, or shift to reverse lunges which most knees prefer
- balance concerns at any age: The supported version is the program, not a compromise — grip lightens as confidence builds
Common questions
Should the rear knee touch the floor?
Approach, not slam — a soft near-touch marks full depth. A folded mat under the knee makes the target kind.
Why is one side so much harder?
Because bodies are asymmetric and two-leg squats let the strong side quietly subsidize the other. Train the weaker side first each set and the gap closes over weeks.
Split squat or lunge — what is the difference?
Feet stay planted here; lunges add stepping. The split squat is the learn-it version, and the lunges inherit its positions in motion.
