When fitness model Mariah Morse isn’t finger-locked with her new man Matt Rife, she’s posted up in the gym, the sauna … or sportin’ bikinis that showcase her toned bod!

Now, Mariah is modeling more sexy stances … only this time, it’s for our scorchin’ Hot Shot photo galleries. Sit back and scroll carefully, because Morse is heatin’ up!

Take a look … and while you’re at it, you’ll notice Mariah loves her fitness regime indeed, but she also loves a good bikini moment!

Beach buns on blast, it’s obvi Rife’s new girl is workin’ hard on her squat thrusts … as she SHOULD, but let’s just hope Rife can handle it 😜!
