This article highlights the importance of viewing the core as a group of muscles that are all interconnected. Doing exercises that involve more of the core muscles will lead to a more effective workout and a stronger core. Not only that, but with the increasing intensity of the multi-joint core exercises, more calories will be burned, resulting in a loss of body fat, and possibly even leading to the appearance of washboard abs.
Good Core Training Takes More than Ab Exercises
Here are a few of my favorite core exercises:
Ab Roller: with a stability ball or with a wheel
Dynamic total body exercises like the bear crawl, inchworm, spiderman, and crab crawl
