Ideal for abdominal training

A Training Equipment, which is for experienced athletes for highly recommended. One should be only after you can keep a certain tension, buy.
I have in the boat a perfect fit and can not empathize with why they are too loose for some. (Probably train these athletes no legs and are starving)
From me there "only" 4/5 stars because the holder is not so good, unfortunately, keeps in thinner rods and one easily begins to vibrate - which creates an unpleasant felt when you think you fall right down.
