Dumbbell Step-Up
Step onto the box with the whole foot and drive up through the leading leg; alternate legs.

How to do it
Setup
Dumbbells at the sides, whole working foot on a knee-height box.
Steps
- Drive through the top foot to stand on the box.
- Touch the other foot lightly, step back down.
- Finish the set on one leg, then switch.
Common mistakes
Bouncing off the floor leg: the bells make cheating tempting; the top leg lifts. Torso folding: tall chest against the load. Knee caving: track the toes.
Breathing
Exhale stepping up, inhale down.
