To lose belly fat and uncover amazing abs, Schuler recommends a series of core stabilization exercises based on a training program devised by co-author and personal trainer Alwyn Cosgrove. "Core exercises like the plank help train muscles to stabilize the spine and pelvis so you can avoid back pain and improve posture, Schuler says. "They also burn more calories than crunches because they work more muscles."
Trade crunches for these three super-effective abs exercises from The New Rules of Lifting for Abs and youll be on your way to a perfectly toned, flatter tummy.
The Best Abs Exercises: Side Plank
Why it works: This abs exercise is more challenging than a traditional plank because you're supporting your entire body weight on two points of contact instead of four. As a result, you must work your core harder to stay stabilized.
