Ok so I find mine at target , i be a woman and I buy the men one , I do not purchase to reduce arm flab I actually purchase to increase endurance\/stamina\/strength in the arm and shoulder as I be a Echocardiographer , basically what that mean be a ultrasound tech that scan the heart , and you guess it ... I have to scan under heavy obese breast ... to get to the heart and no the patient can not always hold they own up they might be unconscious , and anyone that be have one know that we have to push hard between rib pace for extended period to get image -lrb- while hold up those boob with the same arm -rrb- I be a new grad and boy be I in for a surprise at how weak I be !!!!!!!!!!! I can not endure more than 10 minute and not push hard means crappy picture which mean angry cardiologist and we have to do 10 a day for 30 minute each ... yike !! this be my answer . I get the men one because those boob usually weigh more than the female version and I be try to create endurance with that add weight like I say . I have do it two day now and my shoulder , biceps , triceps , pectoral , trap and lat all ache !!! whether or not the flab go anywhere this be definately a good workout for what I need .
