Start with your fingers pointing toward your heels in a reverse plank. Extend your hips toward the ceiling and straighten your arms. Bonus: This works the triceps too! Perform 30 repetitions, tapping the floor with your backside.
Remember, consistency is the key to making changes in your body. In two weeks, you should feel stronger; in six weeks, you might find yourself dropping a jean size!
Keep going strong with all of Andrea's body-toning exercises.
