The Split Squat: Your Stair-Climbing Strength Test

The split squat is a stationary lunge, which is good news if your balance is less “circus acrobat” and more “carrying too many grocery bags.” Stand with one foot forward and the other behind you, feet about hip-width apart—not on a tightrope. Keep most of your weight over the front foot, then lower your body by bending both knees. Push through the whole front foot to stand.

Here’s the useful bit of biomechanics: your front leg should handle most of the load. Your front knee bends while your hip moves downward and slightly back, making the thigh muscles work to control the descent. Your glutes help extend the hip as you rise, and your calf and foot stabilize you. The back leg is there for balance and a little assistance, not to launch you upward like a spring-loaded pogo stick.

Done correctly, you should feel the front thigh and buttock working, with a steady stretch—not a sharp pull—in the back hip. Your torso can lean forward slightly; that’s normal and often helps the front hip do its share. Your front knee may travel past your toes, provided it tracks in the same direction as your second or third toe rather than collapsing inward.

Wrong usually feels obvious: pressure or pain at the front of the knee, wobbling from side to side, or most of the effort happening in the back foot. A knee drifting inward means your hip and foot are losing control. A short, bouncy dip means you’re skipping the part where muscles actually control the movement. Slow down, shorten the range, and use a wall or chair for balance. Sharp pain is a stop sign, not a challenge from the universe.

This week, do two or three sets of eight controlled repetitions per side, resting about a minute between sets. Start with both hands lightly touching a wall; progress to standing free, then hold a dumbbell or backpack at your chest, and finally elevate the front foot on a low step for a deeper range. Move up only when you can lower for three seconds, keep the front knee tracking cleanly, and rise without pushing hard from the back leg. The advanced version is not “deeper at any cost.” It is more load under better control.
