Band Tightness

B Strong Bands should be firm against the limb before there is any air inside. Here are the steps for adjusting the loop prior to inflating:

1. Make sure bands are fully deflated prior to putting them on.
2. Pull the tail strap through the metal loop and pull snug so that the bands cannot rotate or slide freely on the limb. 

If your arm is on the smaller or larger end of the size range, you may experience a gap or overlap which is perfectly normal.  Watch the video in the web app called "Band Placement" for more tips.  

When you have the bands properly tensioned prior to inflation, you will already start to feel some small restriction, and notice some color change in the limb, and have distended veins etc.  You should not tighten as hard as you can, but you do want the bands nice and snug against the skin.
