Dead Bug

Track dead bugs by reps per side, range, and trunk-control notes.

What it is

A floor core drill where opposite arm and leg move while the trunk stays quiet.

Target area

Core, hip control, shoulder control, and coordination.

Why it matters

Dead bugs teach bracing with limb movement, a key skill for beginner strength work.

Step-by-step instructions

Use these cues for app form guide popups and workout-log reminders.

  1. 1Lie on the back with arms up and knees bent over hips.
  2. 2Brace gently while keeping ribs from flaring.
  3. 3Slowly lower one arm and the opposite leg.
  4. 4Return to the start and alternate sides.
  5. 5Use a range that keeps the trunk still.

Common mistakes

  • Moving too fast.
  • Arching the back as the leg lowers.
  • Letting the ribs flare upward.

App-friendly short summary

Track dead bugs by reps per side, range, and trunk-control notes.

Easier version

Move only the arms or only the legs.

Harder version

Straighten the moving leg or pause near the floor.

Safety notes

  • Keep the range small if the back arches.
  • Move slowly enough to breathe.
  • Stop for back or hip pain.

Beginner terms explained

These definitions match the app form-guide popup language.

Brace

Lightly tighten the midsection as if preparing for a cough while still breathing.

Neutral spine

A comfortable spine position that keeps the natural curves without forcing a hard arch or tuck.

Controlled reps

Repetitions performed with steady speed, body control, and no bouncing.
