Is cardio a best fat burner for men? A guy friend of mine starts working out and is now getting addicted to it. Not only does he claims he wanted to lose fat but mainly he wants to buffed up. This is the first time I hear this passion from a gay. Though, it's good he has this nice plan in his lifestyle. He even encouraged me to do cardio to help me lose weight since he did lose weight from doing it. I wanted to go back to the gym too but I just have a conflict of time. And that's so sad.
