Now the interesting bit, years ago 69 to be exact I started playing with rubber a first I think or so people tell me, and Ive never been slow to ask people who knew more than me, there were plenty questions. Im not telling you how but here are a few clues. Your bodys Heart works 35% better Horizontal on your back, also with the tests weve done in the laboratry using certain techniques the body pruduces 30% less latic acid remember lactic shuttle, Fuel. Okay because youre flat gravity isnt such an issue with your venus returns your Heart isnt pumping up less stress plus theres very little impact on joints. Now you can get as much stress and impact three or four days a week as you ever want. But wouldnt it be nice with the rest of your time if you were work and help repair the damage you created and help the body work and adapt to working with less fuel injury free that sounds a good idea, its all done with rubber ,balls and all TBC
