This is a new movement that I created for an advanced core exercise for your programs. Doug Balzarini from Fitness Quest 10 posted a great clip on Elite FTS that had 5 very advanced exercises for the TRX that you may not have seen. I created my exercise after I watched one of his movements and changed it from tricep explosiveness and more towards core stability.
Here is a link to Doug’s article.
I have several more health and fitness ideas that I will be passing your way in the New year!!
