Chances are, joining a gym (or actually getting to the one you already belong to) is on your 2015 to-do list. Instead of hitting the treadmill for the umpteenth year in a row—and dropping off by mid-February—we suggest you spice up your routine instead. Here, a few ways to whip your bottom (arms, legs, and abs) into shape and keep things interesting all year long.
Hit the slopes like Linda Evangelista.
…or the sand like Josephine Skriver.
Work your body on a board like Sigrid Agren.
Hang out like Natasha Poly.
Shake it off like Elsa Hosk.
Turn your routine on its head like Valentina Zelyaeva.
Crush a few balls on the court like Caroline Trentini.
Band together like Romee Strijd.
Make like Toni Garrn on a Megaformer.
Go for a post-“I-ate-the-roof-off-the-gingerbread-house” run like Georgia Hilmer.
Snap a gym selfie—and prove all the naysayers that said you wouldn’t stick to your resolution wrong—like Vanessa Axente.
