Step-Up
Step onto a box and stand up through the working leg without pushing off the floor with the trailing one.
How to do it
Setup
Face a knee-height box, whole foot of the working leg on it.
Steps
- Drive through the top foot to stand on the box.
- Touch the other foot lightly and step back down.
- Finish the set on one leg, then switch.
Common mistakes
Bouncing off the floor leg: it stays passive; the top leg lifts. Knee diving inward: track over the toes. Leaning into the box: tall torso, hips under the shoulders.
Breathing
Exhale stepping up, inhale down.
