Hi, I am currently aiming to get a toned midsection with visible abs, and also get nicer arms and chest. I went on a low-carb diet (eggs,baked beans,steamed chicken,beef steak,bacon,ham,fruits,veggies,few kinds of nuts) and I drink protein whey pre and post workouts. Basically I am having a 3 day biceps-triceps-chest cycle, twice a week, and resting on Sunday. I work my midsection and back on all days as well.

Thing is, I want to increase my fat burning and there are 2 things I want to add into my training. Badminton and Complexes. For badminton, my question is that too much cardio will burn fat but take away muscles as well (which is clearly not what I want) so how much badminton I can actually play to make sure I'm only burning most of the fat and not eating up my muscles?

Second question is that I read that complexes should be done on off-days or cardio days.I want to add some into my training and I am wondering if I can actually add them into my weight-lifting days? I am afraid that adding them to the weight lifting days will eat up my muscle ( like badminton) and also slow down my muscle building.

Thanks.
