Here's the question, do any of you seasoned exercisers who now have achieved good muscle tone and definition do cardio five days a week? I do cardio about 5 days a week, it can go up to 60 minutes, I lift doing one body part, once a week, sometimes legs twice. Is this too much cardio, am I possibly hurting the muscle? I am getting pretty good definition because I like to lift pretty heavy. Is it possible to still achieve nice muscle while doing so much cardio or would you suggest I tone it down. I do still need to lose some bodyfat. I carry mostly around my stomach and behind. Thanks it would be nice to get some differing views or what's worked for different individuals? Thanks
