CrossFit Ab and Core Workouts

The cornerstone of any top CrossFit athlete is their core strength. Without it you can have all the speed in the world but are doomed to fail without a strong core. As the saying goes “Strong Core – Strong Body”.

Greg Glassman, founder of CrossFit describes 3 top ab exercises as the Glute Ham Developer (GHD) situp, hollow rock and L-sits. Read his tips here: CrossFit ab and core article.

Some of those exercises are found in the following workouts that are great ways to build your body. We get asked this question every week “What are the best CrossFit wod’s for abs?”. Of course most of the time you are doing a CrossFit workout (kettle bell swings, deadlifts, etc.) you are working your core. But for those that want a little extra – read on.
