Step-Up

The Step-Up is a unilateral strength exercise where you step onto a raised platform and stand up using mostly one leg at a time. It trains the quadriceps and glutes, with help from the hamstrings, calves, hip stabilizers, and core. Compared with jumping, it is also a lower-impact single-leg option.

Set up facing a sturdy box or bench. Place your entire working foot flat on top so your knee is roughly over your ankle. Keep the other foot on the floor behind you, a soft bend in the standing knee, and your torso tall. If you are loading it, hold dumbbells at your sides, rack a barbell on your back, wear a weighted vest or ruck, or keep your hands free for balance.

Brace your midsection, then drive through the whole foot on the box to straighten that leg and lift your body. Bring your trailing foot up to meet the working foot on top of the box with only a light, brief touch. Then lower yourself back down under control by bending the working leg and placing the trailing foot softly on the floor. Finish all reps on one side, or alternate sides each rep.

Breathe in at the bottom, brace your core, and exhale as you step up. For an easier version, use a lower box and keep a handrail or wall within reach. To make it harder, raise the box height or add a dumbbell, barbell, ruck, or weighted vest while keeping the same controlled descent.

Fault: You push hard off the back leg to get up. Fix: Let the working leg do the work. Keep the trailing foot relaxed and use only a tiny tap or no push-off at all.

Fault: You drop back down with a loud foot slap. Fix: Lower yourself slowly on the working leg until the trailing foot touches the floor gently. The step down should be as controlled as the step up.

Fault: Your knee caves inward or wobbles over the toes. Fix: Drive pressure through the entire foot on the box and push your knee in line with your second toe. If you cannot keep it steady, lower the box height.

Fault: You lean forward or round your back as you step. Fix: Stay tall, keep your ribs stacked over your pelvis, and brace your core before each rep. Use a handrail or wall if balance makes you hunch.
