Actually lifting weights helps you more than cardio does. It speeds up your metabolism. Doing both is great though. You can start light weight lifting now, so that when you want to bulk up you will be ready to start adding weight. Be careful on the supplements though.
My workout schedule has worked pretty well so far. It looks like this:
Mon - Chest
Tues - Back/Biceps
Wed - Off
Thurs - Shoulders/Triceps
Fri - Legs
Abs every day.
I do a 30 minute low intensity cardio training every day except Sunday. I am working up to doing an additional 30 minute cardio training each day too. Just been a lazy procrastinator though.
