Has anyone used the ab wheel and gotten results? And I know that visible abs are a result of low bodyfat. I am more interested in the development of the abs themselves (whether stronger, larger, more defined, etc.) with the ab wheel, not discussing how the body works or how diet is what makes the abs show. I have seen people use it and I am particularly interested in it because of its:
1. Wide range of motion
2. Physics behind why it works
5. Something different
P.S. Yes I searched and there are no thread titles with 'ab wheel' in them.
