A step-down with a band is a slow single leg knee bend on a low step, with a resistance band around the working thigh, just above the knee, pulling the knee inward. You stand on the step on one leg, bend your hip and knee to lower your free foot toward the floor beside the step, and rise back up before it touches. The whole time, you hold the kneecap in line with your second toe against the pull of the band. Physios use it in a lot of knee and hip programs.

How to do the lateral step-down with band

Tie a resistance band to something solid at about knee height, on the side of your other leg. Loop the free end around the thigh of the leg you will work, just above the knee, as in the video.
Stand on a low, sturdy step on the working leg, next to a wall or rail you can touch. Point that foot straight ahead, close to the side edge of the step, and let your other foot hang beside the step. Stand far enough from the anchor that the band already pulls gently.
Squeeze the buttock of the working leg to turn the knee slightly out against the band, until the kneecap lines up with your second toe.
Slowly bend your hip and knee to lower your free foot toward the floor beside the step. Keep the kneecap over your second toe all the way down. A small knee bend is enough to start.
Just before the free foot touches the floor, push through the standing foot to straighten back up.
Do your reps, then move the anchor to the other side and switch legs.

What you should feel

Work in the front of the thigh and the buttock of the standing leg, with the side of that hip working hard to stop the band pulling the knee in.

Common mistakes

Letting the band pull the knee inward, past your big toe.
Twisting the pelvis or trunk to keep the knee straight instead of using the hip.
Dropping fast, or letting the free foot land and take your weight.
Choosing a band so strong or a step so high that you cannot hold the line.

How often

Many programs begin with 2 to 3 sets of 8 to 12 on each leg, with a light band and a low step. Your physio will adjust this and pick the band and step height for you.

Stop and check with your physio if

Sharp pain in the knee, or the knee buckles or gives way.
Pain at the front of the knee that grows rep after rep.
You feel unsteady enough to fall. Hold the wall or rail and step off.

From the clinic

You are on one leg on a raised surface with a band pulling at you, so set up next to a wall or a stair rail every time and keep the floor around the step clear. The anchor has to be solid. A band that slips free snaps back and can throw you off balance, so check the knot before each set. The video is filmed from the front, with the free foot lowering beside the step, which physios often call a lateral step-down. Some programs lower the foot off the front edge instead, with the same knee position, and your physio will tell you which to use.

If the knee keeps drifting in even with a light band, take the band off and practice the movement on its own for a while, or go back to the mini squat and the step up. The backward step-down uses the same knee control with the free foot reaching behind. If you have had a hip replacement, get the go-ahead from your surgeon or physio before you try lateral step-downs. Some operations limit this kind of work for the first months, so the timing depends on your surgery. After knee surgery, wait until your surgeon and physio clear you for single leg step work.
