first of all diet most important if you wana loose those man boobs. im assuming you dont eat your 3 portions of veg and 2 of fruit, do so great place to start. for the veggie side of things eat lots of cabbage, broccoli and colliflower, these veg reduce the oestrogen levels in the body which is a female hormone. which is why u have boobs, because of a rise in oestrogen in your body. secondaly if your doing cv work then use interval training i suggest the rower. do 20sec sprints with 40secs rest. repeat that 12 times that should be your cv work done. resistance training is obviously wot u want to do if you wana get riped for the ladies, its also a great way to loose weight useing a training technique called peripheral heart action, while also getting all the benefits of hypertrophy. give us a private if u want more details.
