Nina Agdal's on Instagram straight flexin'.

The Sports Illustrated cover model took to the social media site to show off her sculpted and toned bod by posting a topless photo of herself that flaunted her back muscle and bulging biceps. OK, maybe not bulging but they're pretty darn impressive.

"#progress skinny doesnt mean weak," Agdal captioned the sexy picture (she is both strong and full of wisdom).

However, it's not totally surprising that the 22-year-old beauty has one super-athletic bod.

Along with maintaining an enviable figure for all of her swimsuit shoots, Agdal showed off her athletic capabilities when she competed for charity recently.

The model and Jeremy Piven, as well as special guest actor and comedian Mario Cantone, competed in the first ever Kiehl's Since 1851 "Ride for Charity" event.

Nina competed in 60-second cycling competitions on Flywheel bikes at the NYC Kiehl's Flagship store against Jeremy, Mario and consumers, and was the clear champion, beating both Jeremy and Mario, while raising funds for Food Bank for NYC.

"Had so much fun riding for charity @FoodBank4NYC with @Flywheel @Kiehls thanks to @jeremypiven for competing with me," Agdal tweeted. Piven responded, "I want a rematch."

Start training now, Piven.
