its really useful since it accomodates just about any size person. plus you can flip around and change the angle on your wrists depending on what suits you best.
I like to face the wide part of the V and drag a toe up and down the 'point''s vertical support to control my body lean.
works great and pretty cheap to make (it was welded by one of my friends and donated to the gym)
Lots of good equipment in that gym, I just wish Debbie would have someone vacuum the floor at least twice a year!
