Plank: Start on your hands and knees and come up into a push-up plank position, balancing on hands (or elbows) and toes (or knees). Align wrists under shoulders; keep your back straight and the abs and glutes tight (to keep the back from sagging). Hold the position and breathe out for 10 seconds, exhaling to tighten the abs and draw the navel to the spine.

It's an all-too-common problem once you hit thirty: Despite your best efforts, you just can't seem to lose the extra weight around your middle, and you look in the mirror wondering what month and year you lost your waistline. Medical research proves you're not alone--that the average American gains one to two pounds a year after age thirty--usually around the stomach. Not only does this excess belly fat make you look and feel bad, it's the most damaging kind of fat; a precursor to heart attacks and certain types of cancer.

"It all depends on your level of fitness, but the great thing is, you can do it whether you're a competitive athlete or just starting out."

I think when we started hosting 'The Doctors' is when the maple syrup diet came out, and it was all about, 'Oh pour a little maple syrup with lemon,' and I was like, 'No, no, that's not going to cure you of all that ails you. I think people need to be careful with celebrities because we always forget … celebrities have a lot of money and access to a lot of things that most normal people don't."
