Guest guest Posted May 14, 2012 Report Share Posted May 14, 2012 Gentlemen, The question has arisen on what “Progressive Resistance†means regarding the Iso-Bow. This is a dual sided statement which can also be termed “regressive†due to the change in resistance during use. Example: When holding a 50 lb barbell next to ones chest; as the arms are extended, the weight of the barbell puts too much pressure on the joints and the arms cannot hold the weight fully extended. Inversely, one can hold 20 lbs at arm’s length, but as the weight moves in towards the chest, the arms are stronger, but there is no way to increase the weight resistance other than changing the weight. By being able to fluctuate the degree of pulling or pushing, one can by using their own strength, increase/decrease the level of contraction to maximize their resistance during a full range of motion movement. This is explained and shown on the Iso-Bow video on the website. http://IsoBow.com This principle also applies to any Iso-Motion movement with a Bullworker and is much more visable in action.
