Library data updated BeginnerBox

What this page is: structured data from Handler's own exercise library — the same cues, mistakes, ranges, and modifications the coach uses in the app. It is general exercise information, not an individual technique assessment or medical advice. Stop any movement that causes pain and seek qualified coaching or clinical care for injuries.

    Push the floor away through the front foot to stand tall.

  4. 04

  • Pushing off the back foot more than the front leg.

  • Letting the front knee cave inward.

Programming defaults

Sets, reps, and rest by goal

These are the starting ranges Handler's library assigns to the step-up for each training goal. They are defaults the coach adjusts from your logged sets, not a prescription for any individual.

  • Switch sides with the same step length.

Working around discomfort

Modifications by body area

How Handler adjusts the step-up when a lifter reports a sensitive area. These are training modifications, not treatment. Pain that persists or worsens needs clinical assessment.

Knee
Shorten the range, keep the knee tracking over the toes, and use a controlled tempo.
Hip
Use a comfortable stance and shorten the range if the front of the hip pinches.
Ankle
Limit jump height or depth and keep landings quiet and stacked.
