Stand all the way up on the box without launching off the floor foot.
Lower the free foot back to the floor with control.
Complete the reps, then switch sides.

Safety

Stop if you feel sharp pain, joint pinch, or symptoms that are not ordinary muscle effort.
This is general technique education, not a personal clearance to train through an injury.
Test the box with your hand before you step. A sliding bench is not a training tool.
