Lateral Step-Down
Stepping down sideways off a box under control — single-leg strength and knee control through a lowering motion.
Also called: step-down, lateral box step-down, box step-down
Setup
Stand on a box or step with one foot, the other leg hanging off the side.
How to do the Lateral Step-Down
- Slowly lower the hanging leg toward the floor by bending the standing knee.
- Lightly tap your heel down without putting weight on it.
- Push back up through the standing leg to return to the top.
- Keep the standing knee tracking in line with your toes throughout.
Lateral Step-Down muscles worked
The Lateral Step-Down works the quads, glutes and hips.
Common Lateral Step-Down mistakes
- Letting the standing knee cave inward.
- Dropping down quickly instead of controlling the descent.
- Using the hanging leg to push off the floor.
Scale it
Easier: Use a lower box, or lightly hold a rail for balance.
Harder: Use a higher box, or slow the descent to 3 seconds.
Pairs well with
Eccentric Step-Down
A slow-lowering step-down that emphasizes the eccentric phase — builds knee control and quad strength for downhill running.
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.
