Get some rocking abs! This is a great exercise that targets your obliques. All you need is a medicine ball or dumbbell. To start: position yourself on a mat. Start with your feet on the ground and your trunk slightly back. Twist to one side, tap the ball, then twist to the opposite side. To make this harder, you can bounce the ball. To make it even harder, lift your feet up off the ground.
Repeat 3 sets for 10 repetitions per side.
