I am a 20 year old moderately active college student who is looking to drop 15-20 pounds. I am dieting and logging my calories in a journal. I have already lost 6 or 7 pounds and I am wondering if I am approaching my trainning the right way, typically I do 45 min to an hour of cardio with a combonation of stairmaster and elyptical followed by 45 minutes of weight trainning. I was wondering in what order should I be doing my cardio/weight trainnning and how many days a week I should be doing each.
