I find it a turnoff whenever men aren't into some kind of sport. And, no, video games don't count. I dated a guy who was into video games, and I wanted to shoot myself.
I'm naturally athletic. I've been involved in sports since I could walk. So, for me to be sedentary is just unacceptable. Not only is it great for your physical body, but it gives me more energy during the day if I've worked out. I feel better. I look better.
I didn't grow up wanting to become an actor at all. I wanted to be a sports trainer and I was actually an aerobics instructor.
