Lunge Twists

  1. Stand upright with a tight core and flat back. Extend arms to chest level in front of you while holding the weight.
  2. Step forward with one leg. Front thigh should be parallel with the floor. Drop the back knee.
  3. Rotate the torso towards the leg that stepped out while keeping arms extended. Push back up to the starting position.

This exercise can be performed with a dumbbell or a plate weight.
