How to do it

Lie on your back with knees bent and hold a weight plate against your chest. Sit all the way up while keeping the plate pinned to your chest, then lower under control back to the floor.

  1. 1Your abs pulling your torso up against the added weight
  2. 2The plate staying tight to your chest throughout the rep
  3. 3A controlled lower rather than dropping back to the floor

Common mistakes

  • Avoid throwing the plate or using momentum to sit up
  • Do not pull on your neck or let the plate drift away from your chest
  • Do not let your feet pop off the floor as you rise

Muscles worked

The otis-up mainly works the upper abs, with the lower abs, hip flexors, and obliques assisting.
