    Ok for some reason every time I go for a run I always feel like I lost muscle mass, my muscles feel smaller and look it. I did some speed work running the other day and after my muscles specifically my chest muscles looked smaller. I am trying to add mass, but does cardio have a negative effect or only certain types of cardio? Thanks!

    Too much cardio is definitely counter-productive to building muscle, but I think a little would be okay. I never do cardio, mainly because Im desperately trying to get ripped, but I also just HATE cardio lol

    No. Variables include caloric intake and caloric spendature. The intensity of the cardio is a major factor in what happens to the calories and where the results will show (weight or muscle gain or loss). It's a balancing act.

    And of course it varies from person to person (metabolism etc.).

    and speed run is not cardio work (speed run as in less than 400 meters).
    My lower body was at his top when I was regulary doing intense speed run ;-)

    Maybe your muscles are just doing what mine are doing and getting tighter?
    I started doing cardio a couple weeks ago, about 3-4 times a week for around 40 minutes burning close to 400 calories a session.
    So far, I've noticed that my muscles have gotten tighter, which may make them smaller, but also my body has become leaner...

    I do a lot of cardio -- I run around 30 miles/week -- and I haven't noticed a loss in muscle mass. I think the cardio helps to make my body look more athletic.

    Cardio in and of itself does not make you lose muscle mass...it's not fueling and refueling properly after doing cardio that makes you lose muscle. But as someone else said you may just be a bit dehydrated.

    the mind perceives things much as it wishes to.

    got the same problem as u man, after a run i actually feel skinnier, however, its blatantly all in our heads, that cant actually happen. its like after a heavy weights sesh, i literally feel ive doubled in size while im in the gym pumpin but as im walkin out the gym door i feel as if ive deflated!! just in the mind, it controls how we perceive ourselves and can drive us mad if u let it.

    Ummm... you reversed the meaning of my post by omitting the picture

    The point illustrated is that NOT all cardio training has the same effect on the body. icon_rolleyes.gif
