Ok , here be the truth as I have no agenda to either endorse or kill this product : I allow myself to get a bit out of shape and as I have finally turn the corner and make marked improvement in my diet and physique , I notice that my upper arm be flabby , and I allow they to become weak . I be skeptical of this product , but I decide to give it a try . when I do the first 6 minute workout , I manage to breeze through it , and I foolishly believe I be in better shape than I think . the next day however prove I wrong , as I find the repetition of the routine actually become harder . I also discover that I do indeed have a weak arm which could not match the other . I feel the burn and fatique after the 6 minute exercise program each time I do it . but then , by week three , I find myself do the 6 minute program 2 or 3 time a day , and though I be still not breeze through it as I do on day 1 , I be manage to complete the entire program . I also be do some add rep on my weak arm and I have manage to balance the two . now , after a month I be not go to say that I be suddenly rip , of course not , but I do notice something . at a moment when I be simply soap my upper arm , I discoverd that they be more `` solid '' and `` tight '' than they be a few short week prior . Let 's face it , you know you own body , so when you discover a change , without even consciously look for one , you become a bit startled . well , I be , and realize that there be some definite toning to my arm . I be also move the shake weight harder than I be thus increase my strength , and try new routine . so , have the product now for about two month , i continue my three 6 minute a day routine and be feel much better do it . I have find that it be a great motivator and one of the few weight regimen that be not boring . after all , if you can not spare at least 6 minute of you day do this program , then what do you want to do ? highly recommend ... ... .
