Step-Up
Stepping onto a box under control — single-leg strength with an obvious carry-over to climbing and hills.
Also called: box step-up, weighted step-up

Setup
Stand facing a sturdy box or bench around knee height. Place one whole foot on it.
How to do the Step-Up
- Drive through the heel of the top foot to lift yourself up — do not push off the bottom leg.
- Stand fully tall on the box before stepping down.
- Lower yourself down slowly on the same working leg — the descent is half the exercise.
- Finish all reps on one side before switching, or alternate deliberately.
Step-Up muscles worked
The Step-Up works the quads and glutes.
Common Step-Up mistakes
- Bouncing off the bottom foot (turns it into a calf raise for the wrong leg).
- Box too high, forcing a torso lurch.
- Dropping off the box instead of lowering under control.
Scale it
Easier: Use a lower step.
Harder: Hold dumbbells, raise the box (knee height max), or slow the step-down.
Pairs well with
Air Squat
The unloaded squat — the foundational lower-body pattern, used for warm-ups, circuits, and building movement quality.
Back Squat
The barbell squat — the heaviest-loadable lower-body strength lift, building quads, glutes, and trunk strength together.
Box Jump
An explosive two-foot jump onto a box with a soft landing — leg power and landing mechanics for stronger, springier strides.
Eccentric Step-Down
A slow-lowering step-down that emphasizes the eccentric phase — builds knee control and quad strength for downhill running.
