The Split Squat Is Better Than You Think (And Probably Wrong)

The split squat—back foot elevated, front leg doing the work—is one of those exercises that looks simple enough that people immediately start screwing it up. I see it constantly: someone puts their back foot on a bench, takes a tiny step forward, then lowers down like they're descending into a hot tub. Controlled. Careful. Wrong.

Here's the biomechanics part, plain version: your front leg is doing roughly 70-80% of the work in a split squat. The back leg is mostly just a stabilizer. When you stand too upright or don't step far enough forward, your torso leans too far over your front knee. That shifts the load away from your leg muscles and dumps it onto your lower back and connective tissues. You're not getting stronger; you're just accumulating wear and tear.

Do it right and here's what it feels like: your torso stays relatively vertical (not perfectly, but close). Your front shin stays mostly vertical too—your knee shouldn't cave inward or shoot way past your toes. When you descend, your back knee should lightly kiss the ground. The burn should be in your front quad and glute. If your lower back is screaming or your knee hurts on the side, you've got the geometry wrong.

The progression is straightforward. Start bodyweight with your back foot on a 12-inch step or bench. Do 8 reps per leg, rest, repeat for 3 sets. Get the position locked in before you add anything. Once that feels solid—meaning you're vertical, stable, and the right muscles are firing—hold dumbbells at your sides. Then progress to heavier dumbbells. After that, a barbell on your shoulders. The load changes; the position doesn't.

This is why split squats beat regular squats for most people working out at home or without fancy equipment. One leg at a time means you're actually addressing strength imbalances instead of letting your stronger leg coast. You need less space. You can load it however you want. And honestly, it's less intimidating than loading up a barbell.

Do 3 sets of 8 per leg, twice a week, and you'll notice your single-leg stability improving within two weeks. That matters if you care about not falling down stairs or pulling something when you step off a curb wrong.
