I have suffered with lower back problems for 20 years , but the last 7 years have been a nightmare. My hips, hamstrings, and upper back were getting so tight due to my lower back problems. I was recommended the grid roller. Initial scepticism was almost immediately replaced with complete and utter joy. Finally a solution.
I had almost been forced to give up surfing due to my back but within a week I was making great strides at getting back in the water, purely down o the grid roller.
The first few times I used it, it was painful as my body was so tight, but now it is almost comforting to use it.
I use it daily, before every surf and any time I have a tight back or body part. It immediately helps. I have recommended it to several friends and they have all benefited from getting one.
I can't recommend it enough. 5 star plus. I would give it ten stars if I could!!
