well, speaking for myself personally, I can say the notion which says cardio makes you lose muscle is bullshit. I'm heavy endo, so if I want to lose fat, I can't starve it off or "just decrease calories". There is a limit to how much you can limit calories before you shut the metabolism down or lose needed nourishment.
You have 2 options:
1. do the cardio and get to the desired bodyfat percentage.
2. listen to all the bullshit about x, y, z, loses muscle and be stuck in a body composition limbo because of it.
Work hard and get to where you want to be.. Good luck.
