Diamond Sit-Up

  • Lie on your back and open your legs into a diamond shape (aka butterfly legs), with the soles of your feet pressed together and knees out wide. Extend the arms overhead.
  • Inhale to curl the torso up, and tap the floor in front of your feet to stretch your glutes a bit.
  • Slowly lower back to the starting position.
  • This counts as one rep.

Technically considered a sit-up, this effective move works the abs through a larger range of motion and adds some functional fitness training to the challenge.
