I want to keep building muscle, while shedding some fat for more definition...?

does cardio take away from your body building gains..if i were to run twice a week and still lift weights would i be doing better (as far as definition) or am i shooting myself in the foot? Athletes and/or bodybuilders only please.

dude try higher reps for the particular muscles or groups you are working arnold in the book pumping iron made fun of the bulked up boys in europe and the fact that they were not doing isolation excercises for particular muscles try the library or go online to a web site for a particular body builders training books iled Frank Zane and Franco Columbo and Arnold back in the day also cardio with wrist wieghts and do twisting motions on the diferant arm or leg muscles the more muscles that are involved the more definition you get.. an olde dude that can press his wieght still..

Cardio is important to any work-out where you plan to lose weight. AT LEAST 30 minutes a day.

As far as your concerns of loosing the gains your trying to make, rest assured, your cardio with your weight lifting routine will give you what you want. You will build up your muscle while sucking back the fat just as you want.

Keep up the hard work, I'm sure your doing great.

I do both at the same time. Keep in mind doing it like this will only let you gain muscle at half the rate of a bulking plan. You'll get lean though.

Right now I eat 60 carbs a day, pay no attention to calories and get 1 gram of protein or more per pound of bodyweight. It is probably better to go lower with the carbs. I built just fine with less.

I do very little cardio, just 1 20 minute session per week. I do high intensity interval training 3 days a week and lift weights 3 days a week. I went from 255 with 135 lean to 239 with 202 lean. I'm still working on it too. I am a 5'11" endo-meso mix, a little more endo though.

cardio does take away from gains. So does going low with the calories. Low carb and HIIT will spare your muscle. If you keep your calories and protein up you can even build. I have been getting about half a pound of muscle gain per week. I used to lose more fat, but now that I am more lean, I am just losing about half a pound a week. I could eat less and lose faster, but then I wouldn't get the muscle gain.

I also take whey protein before and after lifting weights.
