I bought this for a friend who suffers with a very tight and sore mid back area. He has been using this every day and actually uses it when he is driving, just pressing the sore part of his back up against the ball as he drives and he finds it really makes his long drives more comfortable. Great value purchase!

I ordered this ball as I suffer with very tight calves due to running, and tight shoulders after lifting. It is great. I used it after my post-workout stretches and really helped to loosen up my muscles. Worked great the day after too to relieve any especially tight spots.

I find this just perfect for mashing overtight glutes!

Absolutely brilliant, I've had a stubborn upper back muscular problem for 19 years that eventually stopped me training. I have paid hundreds of pounds over that time but my muscle remained tight and problematic. I first bought a foam roller which helps a lot but doesn't penetrate deep enough. After buying this inexpensive little ball and using it whenever the muscle starts getting tight so far I've been able to train again without incident. Try it yourself for any hard to get to muscles. Amazing relief for any tight spots.

Brilliant product for any tightness. I have found it works better in certain areas. Brilliant for glute tightness and upper back.
