I need some advice here guys. Im 17, Im a lean guy 5'8 and 142 lbs i dont remember my body fat % but it has been really low forever. Im currently lifting weights and trying to gain around 10-20 lbs but I'm also parcticing for long distance track which means that I run around 4-5 miles 5 days a week and the other 2 days I jump rope. I read that alot of cardio burns muscle too.
So is it possible to gain muscle mass with so much cardio and still not lose my speed?
