This is definitely one of my favourite crossfit exercises!
It’s a really effective way to build your forearms, and target your core + quads 
My form is still a working progress.
I find it incredibly difficult to hold my stance when my feet hit the bar (when doing multiple reps)
In any case, some of you may be able to do this with ease!
Remember! The slower you do it, the more challenging and effective it becomes.
That looks incredibly hard.
