Danish model Nina Adgal got a chance to show off her backside and pose alongside Chrissy Teigen and Lily Aldridge on the cover of the swimsuit edition of Sports Illustrated, and it's pretty easy to see why she was chosen!
The smokin' hot model is a bit of a gym rat and is OBSESSED with staying in shape!
But instead of simply telling us like she did last time, she decided to show us the results of her hard work and stripped down to show us her insanely toned back with a super sexy Instagram pic!
"#progress skinny doesnt mean weak"
She is NOT lying! Homegurl definitely has some impressive muscles!
We'd definitely say Nina is qualified to grace another cover of Sports Illustrated or two or seven!!
