For those who are just starting out with the sport: This exercise is really tough and you should really pay attention to clean technology and design!
The videos, which floating around on the net, all look easier than they actually are.
Especially the variant are demanded everything from one and sticking with it. Until I manage my first repetition in the stand, pass woohl a few more weeks or months.
Had after the first application massive muscles in the abdomen, which is probably due to the expansion and stretching effect this exercise. The Ab Roller to train his muscles almost entirely static and not dynamic, such as in crunches.
About the device itself:
The device is very small and handy. Processing (albeit entirely of plastick) is also managed.
The handles offer by gumming enough grip, the wheels do not squeak (yet) and the handles also bend not (I weigh Kg 102K).
