There’s definitely something to this!
After developing piriformis difficulties as a result of a referred nerve pain from my back, I have been trying everything under the sun to feel better. A friend recommended I try the back baller, apparently it was becoming popular in her brother’s GAA club. I live in the UK but they shipped with free p&p. After two weeks going through the programme, I can honestly say I’m noticing a positive change. It’s sore, particularly in areas which need more attention but so easy to use and very compact. I cannot recommend this highly enough.
