Do you roll out on a foam roll to loosen up your tight tissues only to find that everything is tight again the next day? There is a very good (scientific) reason for that. A foam roller will never give enough pressure to break up scar tissue, adhesions, or trigger points, regardless of what someone has told you in the past.
I’m not saying rolling out on a foam roller is bad for you, as it still has some good uses.
Foam rolling does a couple things for you.
A good rule of thumb, roll out an area for 30 seconds, then actively use e area you just rolled out through its full range of motion, and then load it. For example, if you roll out your hamstrings, follow it up by doing some active straight leg raises lying on your back, and then some light good mornings with an empty bar.
