Toning muscles is a function of
fat loss... so you're really looking to do the same thing... I believe the only way you will 'get huge' is if you have a calorie surplus... so you probably won't be in much danger of that if you're watching your
diet.
tonymclellan, one of the resident experts, has suggested the book The New Rules of Lifting, a few times around here (i can't remember who wrote it and Idon't have the
energy to open my backpack) that's gives a lot of helpful info and some what l ook to be good workouts (I could be wrong - looking for the perfect book is my quest for the holy grail)
Cardio, I believe is important for
fat loss, but rather tahn sustained
cardio, you want to work on interval type training or
HIIT training (youll find a few threads on that here) where you are changing up speeds and making yourself work a little harder. the lovely Steve's diary also has a ton of helpful info (in between all the chatter)
good luck
