Having been doing some planks recently it occurred to me that a normal face down plank is more of an antagonist excise for climbing and that training with a reverse plank may be a more appropriate for stopping your @rse sagging away from steep rock.
How is it I never hear anyone bestowing the virtues of doing reverse planks?
I get it that the normal plank will help with getting your feet back on to the rock, if you've cut loose...
