Sleeper Stretch
The key to this unique stretch used by our therapists at Tri-Covery is called strain-counter strain.
Which means, go to a position that causes minor discomfort and hold it for thirty seconds, then release.
The next time you go into the position of minor discomfort it has changed and you should be able to push a little further before you find the discomfort again.
Doing this a few times will not only improve range of motion, but it will also release adhesions and the reformation of scar tissue.
