After searching for many hours how to solve my problem I came across the PowerBall so I decided to order this basic model to give me a idea.
Some uses already sufficient to remove all or part of the pain!
A companion whom I can not separate myself!
Also the small tachometer is very playful although far from essential, it can be used to set goals.
Note however that going as soon as possible does not make much sense to remove the pain, it is the repetition of exercises that moderate speed is more important!
