Memorial Day is gone and so is your trim waistline. You don't have time to fool around with silly ab routines now. You need something that works.
So how about the best ab exercise known to man? Or at least to a reputable scientific journal?
It's called a combination swiss ball pike and roll-out.
Sounds like a medieval torture device. But it's actually easy to learn and extremely efficient. In fact, you can probably get a killer ab workout by doing this move fewer than 10 times.
"If someone was looking at one exercise and wanted to make sure he was getting the most abdominal work done in a way that makes him look better and function better," says trainer Nick Tumminello, "this is the exercise to do."
To start the pike/roll-out, simply hold yourself in a pushup position with your feet on a swiss ball. (To make the exercise easier, move the swiss ball towards your belly button) With your body in a plank (straight) position, keep your legs straight and push your hips towards the ceiling while keeping your back flat. After straightening your hips and coming back to the start position, push your body backwards on the ball until your arms are fully extended in front of you and your legs are fully extended behind you.
