Stability Ball Oblique Crunch
A side crunch draped over a stability ball to zero in on the obliques. Lifting your torso up toward the hip against the ball's roll builds strength and definition along your waist. The instability makes it more effective than the same crunch done on the floor.
How to do it
- 1
Rest your lower back and hips on the ball with both hands behind your head.
- 2
Engage the core to lift your torso off the ball.
- 3
Twist toward one side so your elbow arcs across toward the opposite knee.
- 4
Hold briefly at the top of the twist, keeping the abs tight.
- 5
Lower back down slowly without losing tension.
- 6
Alternate sides each rep and stay braced throughout.
