Regarding the former, wrapping with 50 percent tension you don’t mess up circulation. And once you remove the floss, the blood flow to that area will actually be increased, promoting healing/recovery.

Banded distractions are perfectly safe if: 

1) you only go far enough to put the muscles under tension

2) you stop if you feel like something is going to tear (K-Star’s rule: if it feels sketchy it is sketchy)

3) you avoid distracting joints which are hyper mobile

Other than that, distract and floss away!
