Shirtless running rocks! I used to it all the time, just because of how cooling it felt.

But about those shirtless men? You never can tell! I’ve actually had TWO hot flings with men I met running.

Oh, and wanna know another reason why running is cool as hell? You won’t understand this yet given your age. ;-) But as we men get on in life, our levels of testosterone can start to drop.

Running, especially when intense sprints are involved, can up testosterone levels a LOT, potentially making a middle-aged man feel sexier and more vigorous.

I can attest!
