Kate Upton Instagram – This nifty exercise truly works the entire back side of the body, all with very little stress on the joints. We’ve been doing it for 10+ years without knowing what to call it, so whoever comes up with the best name in the comments wins a prize. @kateupton makes it look easy, but trust me—it’s a toughie. From an upper body standpoint, it starts off as a pull-up but turns into an inverted row at the top. From a lower body standpoint, it starts off as a leg curl but turns into a hip thrust at the top. So, a whole lotta good things happening here. Plus it gets the heart rate up like crazy, too. First give us a name for the exercise so I don’t have to keep referring to it as the “pull-up mega hip thrust thingy,” and then give it a try because I think you’ll really like it.
