im on my first cycle,and on my 8th of ten days,by the time the week is over I will have done cardio 7 out of ten days,cheated a bit on diet last weekend,but so dar only lost 2lbs,Im sure its more once I drop water.but even if its only 2lb I think it was worth it,I didnt get tired like most,just had trouble getting to sleep a few nights and sweat like hell
