Who's Inspi(red)?

Why it's none other than gym bunny Charlize Theron! Actually, I can't remember the last time I've seen her heading to a work out. Perfectly beautiful creatures don't need to exercise anyway! But props to Charlize for making an effort.

Sidebar, is that a wedding/engagement ring on her finger? I know she doesn't want to get married until everyone can, but still - it's a gold band!
