Foam roller - Necessary ? 
=========================
Foam roller is a new hype in fitness industry but does they work? 
According to a 2017 study, it does improve range of motion if done before exercise but there is no difference in strength 
And also no need of doing it for hours, just some light warm up with a foam roller is fine.
