Target Muscles

Instructions

  1. Lie on your back with one knee bent and the arm on the same side extended directly over your shoulder, holding a dumbbell. Your opposite leg should be directly in front of you, and your opposite arm should be at your side.
  2. From this position, sit fully upright, lift the dumbbell toward the ceiling, and extend the opposite arm in front of you, parallel to the floor. Pause and roll onto the floor, holding the dumbbell up.

Tips

  • Always keep your neck in line with your spine.
  • Use your full range of motion and let your body descend completely to the starting position.
  • Don't use momentum to help with the movement.
