Stickie enjoys having a trim waistline. She knows that working her oblique abdominals contributes to that trimness, so she often chooses to do Russian twists. (Stickie is a fan of Lemony Snicket, who would point out that “Russian” in this context means “horrible, challenging, or painful, but effective.”)
She begins seated on the floor with her knees bent, feet flat on the floor. She holds a medicine ball (a dumbbell will also work just fine). Her torso is slightly leaned back, her abs drawn in. Keeping both hips firmly planted on the ground, she twists her upper body to one side, touching the medicine ball to the floor next to her hip. She quickly twists to the other side and does the same. A touch on both sides makes a single repetition. Sets of ten repetitions are good. Stickie does two or three sets.
