Library data updated BeginnerDumbbell

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.

Working around discomfort

Modifications by body area

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

Wrist
Use a neutral wrist position or reduce loading until the wrist stays quiet.
Elbow
Use a softer lockout and stop before elbow discomfort changes your tempo.
