When a mega celebrity breaks up with you and dates another mega celebrity before you can even delete all your relationship Instagrams, there's only one thing to do: Work on your revenge bod.

Calvin Harris is quite obviously all over this and has been taking to his Snapchat to post videos predominantly about leg day. He also does some indoor cycling:

I never though I'd live in a world where Calvin and Tom Hiddleston would be pitted against each other, but here we are. At least they're making an ab-tastic spectacle about it.

Long story short, it's time to follow Calvy on Snapchat. Oh, and never neglect leg day. He will yell at you.
