I want to buy a foam roller and massage ball for self massage and myofascial release. What are things/features to look out for when buying these? Also, is it worth to invest in a known brand or do the cheap ones do the trick as well?
You may want to select the type depending on your purpose such as Grid, For Physical Therapy, Half Roller, Stick, and Vibrating. Get 24 inch foam roller for your arms/legs and 36 inch for your back.
