I agree with sgt!! When I was trying to lose weight I did a lot of fasting cardio first thing in the morning!! Then weights a couple times a week!! And more importantly a strict diet!!:)

Fasted HIT is is good . i do it to really get shredded so i fast for 20hrs and eat for 4 its no easy task especially when other members in the house are cooking food and thats all you can smell. Cardio say for 20min then weight training for 45min very short rest say 60sec inbetween sets. i still spew occasionally especially on my leg days not that that's a good thing but that's the intensity im talking about. this style of training will sort girls out from the women lol..

Woman dont grow muscles like men they lack the hormones we do. The best looking woman in the gym are the ones who are busting their ass lifting heavy weight and not the pink dumbbells. Weight training then cardio. I would start her off slow woman take very well to circuit workout espcially to drop weight always keep the intensity a little higher for them
