How to do it

Sit on the floor and lean back slightly, lifting your straight or bent legs off the ground so your body forms a V balanced on your sit bones. Reach your arms forward alongside your shins and hold the position.

  1. 1Feel your deep abs working to hold your torso and legs up in the V
  2. 2Keep your chest lifted and spine long rather than slumping back
  3. 3Breathe steadily and hold a stable balance point

Common mistakes

  • Don't round your back and collapse your chest
  • Avoid holding your breath to brace; keep breathing
  • Don't let your legs drift down as you fatigue

Muscles worked

The boat stretch mainly works the lower abs, upper abs, and hip flexors, with the obliques and quads assisting.
