2 short videos to the first use of your B 3 bands.
It is VERY IMPORTANT after EVERY use of your bands that you make sure ALL the air is out of the chambers.
So the B3 bands lay FLAT.
You can damage the bands if you do not do this after each use.
After letting the air out with the valve..I usually after I take the bands off fold then in half and press down on them wile holding the valve open.This makes sure ALL the air is out of the multi chambers.
This how you take care of your bands.
This is not a full training. Below is how to use the pump and the valve on the bands.
