No one embodies swimsuit-ready quite like Nina Agdal. The Danish model, 24, always looks toned and fit, whether she's relaxing beachside with boyfriend Leonardo DiCaprio or stunning in the pages of Sports Illustrated Swimsuit (she landed the coveted cover spot alongside Lily Aldridge and Chrissy Teigen in 2014, and also appeared in the 2015 and 2016 issues). So we were dying to know how Nina stays so sculpted, especially given her busy schedule traveling for gigs.
