Library data updated BeginnerBodyweight

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.

Technique

Form cues for the dead bug

  1. 01

    Exhale gently to set your ribs down before each rep or hold.

  2. 02

    Brace like you are about to be bumped from the side.

  3. 03

    Move slowly enough that your low back position does not change.

  4. 04

    Move opposite arm and leg only as far as your back stays quiet.

Troubleshooting

Common mistakes

  • Holding your breath the entire time.

  • Letting the low back arch.

  • Moving faster than you can brace.

Programming defaults

Sets, reps, and rest by goal

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

Between sets

  • Quality bracing beats longer sloppy holds.
  • Stand up or breathe tall between sets.

Working around discomfort

Modifications by body area

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

Lower back
Reduce load, brace before each rep, and stop if you cannot keep a neutral spine.
Hip
Use a comfortable stance and shorten the range if the front of the hip pinches.
