I did my first workout with this series lastnight and all I can say is these workouts are killer. I consider myself in pretty good shape cardio wise and I was dying. I dont know if I myself want to workout that hard. OMG! I told myself I would complete at least a week and then decide. I cant beleive how hard these are, if one doesnt see results from these workouts there is something wrong. and if someone doesnt that would be me, thats usually how it goes for me but if I dont lose wt from these I wouldnt know what else to do besides clean eating. How many calories should you eat when doing this program. I am 5 2 1/2 134 lbs, 40 yrs old. thanks
