Re-train your soft tissues and neurology to hold the adjustment.
Correct forward head posture and overall posture.
Relieve tension on the spinal cord, helping energy to flow easier from the brain into the body.
Relieve stress and tension on the heart.
Promote tissue oxygenation by increasing lung capacity.
Relieve pressure and stress on degenerative discs so they can re-hydreate and regenerate.
When you wear your head weights, the weight must be front and centre, sitting at the highest part of your forehead. Note, they must not sit "on top" of your head.
You can put up to two weights in each pouch of the Velcro strap. Whether you are using 1,2,3, or 4 pound, centre the weight accordingly so it is balanced (i.e. to load 4 pound, place 2 weights in the centre pouch, and one on each side).
Tighten the Velcro strap so that the head weights do not move (but not to the point that the headband hurts).
You can wear the head weights on the brim of a baseball cap if you have long hair (which makes it difficult to tighten the Velcro strap), or if you have trouble keeping the head weights on.
When worn immediately after adjustment, the weighting system will help you HOLD AND STABILIZE your correction longer. They will accelerate your results and create a more permanent correction.
Preferably, use the head weights standing while walking or moving. Alternatively, you may use the head weights sitting upright. Do NOT use your head weights sitting at a desk, on the couch, washing dishes, etc.
Your neck muscles should not hurt, but should be "tired" when first using your head weights. Much like weak arms that have never lifted a barbell, these muscles are greatly under-utilized and will require some time to build up strength. With persistence, you will eventually reach the point that you don't even realize you are wearing the head weights.
