I’m off to teach my two classes this morning and then celebrate my birthday today, so give this workout from Mark from LiveStrong!

Nowadays most everybody wants 6-pack abs, but many individuals don’t fully understand how to properly go about building a chiseled core. If you’re like most Americans, you likely watched the 2012 Summer Olympics in London. If so, you probably noticed 99% of the male swimmers were flaunting pretty shredded midsections. Yes, they work their core consistently, but I’m willing to bet most of this definition results from intense aerobic training. Let me state the obvious: the lower your body fat percentage, the more defined you’ll appear. However, it’s important to appropriately achieve lower body fat by eating healthy, maintaining muscle strength, and training aerobically.

But I’ve talked enough; let’s get to the good stuff… What you’ll need: elliptical machine / treadmill / recumbent bike /other stationary cardio machine, an area where you can lay on the ground, your person, and a positive attitude

** I recommend stretching for 15 minutes prior to starting the workout

** Gradually increase resistance / intensity over time if you repeat this workout

** This workout is meant to be constant without breaks but take them if you need them – push yourself!
