do the foam roller come in different sizes? I need to get one but need advice on the best choice.
I bought a short one, which was a mistake. I really like it, but you can't do several of the upper back exercises. My advice is to get a 36" roller. You should be able to lie upon it so that when it is parallel with your spine both your lumbar and neck are supported. It's nice to have a short one, too, but these things are ridiculously overpriced. If you have to get one, buy it on amazon or get it used.
