And also generally terrible. People end up using them purely for the endorphin rush they provide from use rather than gaining any actualy benefit from them
@SoliD: Why do you feel you need to experience pain in order to believe the roller is providing any benefit?
Yup - if you are not getting pain then this is possibly a good thing. Because where do you stop? I had to use a rolling pin a few months ago, but then reverted to a better training and mobility regime and weirdly all my problems disappeared.
Have a think about your training (cycling technique, and the fact that your legs are not as strong, balanced or mobile as you think), diet and recovery (rest is important!) and you may find you are served much better.
