Welcome to the boards lars.

As far as getting rid of man boobs I don't think there is much you can do to really target fat loss specifically in that area. It is possible that you have gyno, but I am sure it is just your body holding onto the fat stores in your chest as many men store fat there. You could try to fill out your chest more with strength training so that it isn't as obvious and flattens out the area or maybe try a topical fat loss to the area like Lipoderm-Y. But I think your best bet is to just continue doing your exercises (make sure you use your upper body during cardio) and have a clean diet. Eventually they should disappear.
