Directions
Start in a seated position. Lower body resting head and shoulders on ball. Activate core muscles holding center of body in an upright position. Visualize making a bridge with your body. Position your hands at a 90 degree angle. PRESS upward in a slow controlled motion. When returning to starting position do not let weights drop below the 90 degree angle. Once reps are complete, place weights on ground and roll back up to starting position.
