EXERCISE VIDEO DEMO: If you workout or hit the gym regularly you probably already have your favorite abs exercises. I don't think there's a guy or girl out there who wouldn't like to strut around the gym with tight abs and a toned core. In order to get those sexy v shaped abs however, you gotta mix up your workout from time to time. This is one of my favorite abs / core exercises that not only tightens up your core, it works your butt as well. In this video I demo how to do a compound hip dip exercise with a clamshell. V shaped abs are also called the Adonis Belt and it refers to the Illiac Furrow which are the sexy little grooves you can develop on either side of your abs. I like this compound movement because it hit the lower abs and really blasts the obliques and glutes in one fluid movement.
