“I started using this foam roller a few days ago, and all I can say is "wow!!!" I love the three different intensities...it's like having three different foam rollers in a size that easily fits into my suitcase for travel. It really is the best of both worlds, as I have found I need different foam rollers in order to roll out different muscles, and this covers it all. I'm so grateful to have found this!!! theROCK Foam Roller, Michael R.
