How to do:
1. Stand up straight and hold a dumbbell in one hand. The free hand can dangle along side your body or be placed behind your head.
2. Bend sideways holding your pelvis very firm. The shoulder of the arm holding the dumbbell should bend toward the floor
. 3. When you reach a point where you cannot bend further, inhale, hold your breath and raise yourself back to the erect starting position exhaling when you reach the vertical position.
4. Repeat this movement several times before switching to the opposite arm.
