sorry i am in my last semester at uk and have a job so it takes me sometime. i do 30 minutes 3 to 4 days a week and that seems to work well. i see gains and loss at the same time. you dont wanna over cardio to where your body is using muscle for energy but just enough and you gotta kinda work that out, but that is what i do. a lot of these smucks say you can't gain and lose but most of these guys wanna look like ronnie coleman. i dont, more like mens fitness body type. but a little body fat is good because that is where your muscles build from and also protein. so keep it up and develop your own workout style, gather some tips and suggestions from others but everybodies body is different. for example my body produces alot of test so i dont do all that supplement shit and break my wallet, just good ol' protein. so work out the kinks and you'll be on the right track.
