Pumping and humping: Kate Upton's Sunday gym session may be her hottest one yet

Model Kate Upton is 'pumping and humping' in her newest Instagram workout video.

Kate Upton is not only a 'total badass in the gym,' but she also happens to have a way with creating unforgettable hashtags.

In what has easily become our favorite fitness series on Instagram, Kate posted yet another hip-thrusting video on Sunday that has the Internet trying to figure out how lifting weights can look SO HOT.  The former SI Swimsuit cover model captioned the video with "I like to start my morning #pumpingandhumping @benbrunotraining."

Talk about a serious dose of #MondayMotivation. Kate has been getting into crazy awesome shape the last six months, showing off how seriously she takes her kegels, and even letting fans in on the secrets behind her notorious beach bod. 

So the next time you find yourself thinking how easy it must be to be a model, we encourage you to scroll back through Kate's Instagram feed. Because what you sweat is clearly what you get.
