Our bands are designed to only be used in two locations, your arms and legs.
The bands are placed high up, above the bicep and below the deltoid. The bands are designed thin enough to get above the bicep so that when the bicep contracts, the bands allow some expansion of the muscle. If you experience any kind of pain, it is likely because the bands are placed too low.
The bands are placed as high up on the quad as is comfortable. For both arms and legs, the white valve should be pointing inward toward the opposite side of your body and if there is a gap between the two ends of the bladder, this should be rotated so it is on the outside surface of the limb.
The reason bands are only placed in these two locations is that it allows us to restrict flow to the maximum amount of muscle mass. B Strong produces a systemic effect which means your whole body will benefit from the exercise if you are doing exercises that engage core and trunk muscles. So, if you are looking to improve calf or ankle function, you don't put the bands around the calf as this leaves out the large quad and hamstring muscles and will produce a minimal systemic effect.
