Step-Up
The step-up is a single-leg exercise in which you step onto a box or bench and stand up on it using the front leg. It works the quadriceps and glutes, with the gluteus medius holding the hip and knee steady on one leg.
Also called: Bodyweight Step-Up, Box Step-Up, Bench Step-Up · Equipment: bodyweight · Pattern: squat
Step by step
- Stand facing a sturdy box or bench no higher than knee height, close enough to step onto it without reaching.
- Place your whole lead foot on the box, heel included, with your knee in line with your toes.
- Lean your torso slightly forward over the lead leg and push through the whole lead foot to stand up onto the box. Keep your back toes light so the lead leg does the work.
- Stand tall on top with your lead hip and knee fully straight. Bring the trailing foot up beside it, or let it hover.
- Step the trailing foot back to the floor slowly, keeping your weight on the lead leg so it controls the descent.
- Complete all reps on one leg, then switch legs, or alternate legs each rep.
- Drive through your whole lead foot
- Knee in line with your toes
- Back foot light, lead leg does the work
- Stand tall at the top
- Step down slowly

What goes wrong, and the fix
Pushing off the back foot
Fix: Keep your back toes light and drive up with the lead leg only.
Knee caving inwards
Fix: Keep your lead knee pointing over your middle toes all the way up.
Box too high
Fix: Use a box no higher than knee height so you can stand up without twisting.
Only part of the foot on the box
Fix: Place your whole foot on the box, heel included, before each rep.
Dropping off the box
Fix: Step down slowly, controlling the descent with the lead leg.
Not standing fully tall
Fix: Straighten your lead hip and knee fully at the top of every rep.
What the research says
Rehab & prehab · first choiceGeneral fitness · first choiceEndurance · first choiceFat loss & conditioning · first choiceSport performance
- Muscle activity — EMG studies of single-leg exercises including the step-up record the highest activity in the quadriceps, followed by the gluteus medius and gluteus maximus. A review of glute EMG places the forward step-up among the higher glute activators.
- Variations — An EMG study of loaded step-ups found the standard forward step-up gave the greatest glute and hamstring activity of four variations, while the crossover step-up gave the greatest gluteus medius activity on the way up.
- Rep ranges — Research finds lighter, higher-rep work favours local muscular endurance. With light loads, a training study found that taking sets close to failure mattered more for muscle growth than it did with heavy loads.
- Progression — A trial comparing methods found that adding reps and adding load gave similar muscle growth. Common progressions are more reps, then holding dumbbells or a kettlebell.
- Box height — There is no direct research comparing step-up box heights. A common approach is a box no higher than knee height.
