All the single ladies! Fresh-on-the-market Kourtney Kardashian and Larsa Pippen hit the gym for a sweaty Saturday workout. I mean, these two have gotta keep fit so they're ready for the next young men who comes into their lives.

Seems Kourt and the much-younger Luka Sabbat have cooled and Larsa just filed for divorce from basketballer hubby Scottie (after going back-and-forth on that for a few years).

It wasn't all work for the ladies -- both stopped to check their phones and send some texts numerous times during the workout. Perhaps hitting up some new men?!
