When thinking about my ab routine or what I may give to my clients, I usually break it down by dynamic vs. isometric. What's the difference? Dynamic represents any ab exercises that you physically move through a full range of motion to execute the activity. Isometric exercises typically represent any position that held without changing the muscles or joints' length while contracted.
The one in the video above is a variation of an oldie, Ab Roll Outs. About the category of core exercises that it falls into, this is a dynamic one. Most of you might have seen this demonstration on my social media feed. This movement is fantastic and had me sore for two days. Believe it, when done correctly, it will rip up your midsection in minutes!
Here's how to do the Ab Rollouts.
Note that you can complete this version of the exercise with an ab-dolly, Val slides, suspension trainer, or a stability ball.
