(Claim 9 & 11 / Paragraph 108) Bowman does not expressly disclose wherein the exercise data indicates a sequence of exercise movements to be performed sequentially by the user, and wherein the electronic device determines that the pressure within the air bladder needs controlling for the next exercise movement in the sequence. It would have been prima facie obvious to one of ordinary skill in the art prior to the effective filing date to further modify Bowman to include wherein the exercise data indicates a sequence of exercise movements to be performed sequentially by the user, and wherein the electronic device determines that the pressure within the air bladder needs controlling for the next exercise movement in the sequence as it would ensure the air bladder is activated based on the pressure that is exerted. (Claim 9 & 11 / Paragraph 108) Meaning, if an exercise is changed, the air bladder will still be activated as it constantly measures the pressure and determine if the pump needs to be activated or deactivated to stabilize the pressure no matter the exercise.
