How to do it

Starting position

  1. Lie on the mat and extend your arms straight overhead.
  2. Bring your legs together, keep your knees straight, and lift them slightly off the floor.
  3. Look at the ceiling and inhale deeply through your nose.

Movement

  1. Brace your abs firmly and lift your upper body and legs upward simultaneously.
  2. When your body forms a V, reach your fingertips toward your toes.
  3. Slowly return to the starting position while maintaining tension in your abs.

Breathing

Exhale as you raise your upper body and inhale as you lower it.

Trainer tips

  • Reach your fingertips toward your toes
  • Lift with your abs without using lower back momentum
  • Lower slowly under control

Cautions

  • Your tailbone can hit the floor hard and cause pain, so use a thick mat.
  • When lowering your legs, brace your abs firmly so your lower back does not lift off the floor.
  • Bouncing back up with momentum
  • Excessively overarching the lower back
  • Straining the neck to tuck the chin
