- Place sandbag or medicine ball between ankles. Lay torso
and waist on bench and grasp handles. Feet should be above floor
with legs straight.
- Raise weight by extending hips as high as possible until
legs are nearly straight. Lower legs to original position. Repeat.

spine), in which case Erector Spinea also becomes synergist.
