We've been performing some rehabilitation and strengthening exercises for his knee and a foam roiler has been an inregral part of the rehab. I recommend that before you consider buying a foam roller that you find out how to use it properly first.
The 66Fit elite Foam Roller is what I use most of the time. It is an excellent combination of firmness and maliability, that provides enough pressure for most people to manage with this foam roller.
The Fit66 elite foam roller is big enough in both circumference and length to get into most muscles including hamstrings.
I have used this foam roller on a range of clients for everything from lateral and mefial knee pain, rec fem and hamstring, ITB and even lats, pecs and spinal mobility.
Having read other foam roller reviews I can certainly recommend the 66fit elite if you are considering buying a foam roller.
Sonia - Physiotherapist in Bristol - has very kindly put together this demo of how to use a foam roller, and I hope that if you are considering buying a foam roller then the advice below will be useful and relevant.
