Box step-up

How to do the dumbbell box step-up: box height, how to drive with the top leg, common mistakes and progression.

The step-up means stepping onto a bench or box with one leg and stepping back down. It is a very functional single-leg exercise, similar to climbing stairs, that trains each leg's glutes and quads separately and improves balance.

Muscles worked

The glutes and quads of the stepping leg are the main movers. The higher the box, the more the glutes work. The adductors and glute medius stabilize the knee.

How to do it

1. Choose a stable box or bench at a height that puts your knee at about 90° when your foot is on top.
2. Holding a dumbbell in each hand, place your whole foot on the box.
3. Push through the heel of the top leg to step up, without pushing off the bottom leg.
4. Finish standing tall on top, hips extended.
5. Step down with control using the same bottom leg and repeat. Finish one side, then switch.

Common mistakes

• Pushing off the bottom leg: the work stops being done by the top leg.
• Box too high, forcing you to lean far forward or round your back.
• Knee caving in as you step up.
• Dropping down.

Progression

Start with no weight and a low box. Then add dumbbells or raise the height. It works well for 8–12 reps per leg.

Precautions

It loads the ankle, knee and hip of the working leg. With knee discomfort, use a lower box. With an ankle injury, choose the hip thrust or the glute bridge.
