How to do it

Lie on your back with arms reaching toward the ceiling and hips and knees bent to 90 degrees. Press your lower back into the floor and brace, then slowly extend your opposite arm and leg toward the floor without losing that flat back. Return and alternate sides under control.

  1. 1Feel your deep core stay braced as the limbs extend
  2. 2Press your lower back flat into the floor throughout
  3. 3Move the opposite arm and leg slowly and under control

Common mistakes

  • Do not let your lower back arch off the floor
  • Avoid rushing the limbs out and losing the brace
  • Do not hold your breath; breathe steadily as you move

The dead bug mainly works the lower abs, upper abs, and obliques, with the hip flexors assisting.
