Wrong - Do not allow the dumbbell to drift to one side of the body.
Correct - Lie flat on your stomach, resting your head on your forearms. Grasp the dumbbell with your feet firmly and lift it toward the butt by bending the knees. Stay in a straight line. Begin with a very small weight until you learn to grasp the dumbbell securely with your feet. |
