You will complete the same motion as a hip raise, but twisting from left to right engages the obliques. While this can be done on a bench, you can also complete this exercise on the floor.
- Lie on your back, and hold onto the sides of the bench behind you. Or, if you are lying on the floor, rest your arms on each side, with your palms pressing down into the floor. Keeping your legs together, raise the legs up toward the ceiling.
- Squeezing the legs together, lift your hips and lower back off the bench, making sure the legs point directly up as you lift and twist toward the left. Return to the center, and slowly lower back down to the bench, one vertebra at a time. Lift up and repeat on the right side.
- Complete two to three sets of 10 hip raises with a twist.
