I’m not typically one to write man candy posts—though, I have been known to tweet pictures of Alexander Skarsgard for midday pick-me-ups—but when it’s shirtless guys with a purpose I just can’t help myself.

Rethink Breast Cancer has introduced a great new (and free!) mobile app to remind women to perform monthly self examinations for breast cancer. (This is the good cause part.) To explain how to do your monthly screening and teach you about the app, they’ve brought together several hot guys. (Man candy part.) Said hot guys do undress a bit.

Abs galore.

Watch the video. Enjoy the abs. And, really, make sure to do the monthly checks. Maybe download that app for reminders from the fellas.
