Supermodel Karlie Kloss and Pastry Chef Christina Tosi Collaborate on a Cookie-Workout Video

Supermodel Karlie Kloss already hawks her own line of healthy sweets, karlie’s kookies, at Christina Tosi’s Momofuku Milk Bar. Now the pair have teamed up to shoot Perfect 10, a fun homage to Jane Fonda-style workout videos.

The short clip was filmed for the latest issue of Lucky Peach and it’s complete with neon leotards, fanny packs, and a guest appearance from the spandex-loving chef of Mission Chinese Food, Danny Bowien.

After the crew finishes up a round of milk-crate step aerobics at the Milk Bar commissary kitchen, Tosi and Kloss cool down by baking cookies — the Perfect 10 is made with almond flour and oatmeal, studded with slivered almonds and chocolate chips.
