I be a little embarrassed about buy something so hokey expect it to work a miracle . I have be use it six minute twice a day . it take about two week to get up to six minute , it be not that easy . I be in my late 50 's and my upper arm have no shape at all . I have try free weight and tone exercise but any woman over 50 know it be almost impossible to see result enough to stay motivated . it be be six week and my uupper arm look better then they have ever look . I have not wear a sleeveless top in decade , now I wear they all the time . Laugh and scoff all you like about this silly thing but if use every day you will get result . I now do not mind use heavier free weight to get more definition but I do not mind if I do not , I be happy with no flab arm , definition or not .
