Welcome to our latest feature, the Weekend Workout. Part winter doldrums eliminator, part incentive to use your recurring days off for something other than lounging, consider this a cheaper alternative to the gym concierge service everyone was talking about last week. No, we won't storm your bedroom to make you do it, but just knowing that it's on all our collective minds might keep you more accountable.

The first installment comes courtesy of ModelFit. A key ingredient in what makes Victoria's Secret girls so angelic, the ModelFit technique uses small movements and a ton of repetitions to sculpt you into something a bit closer to Karlie. To prove that these workouts really can be done at home when there's literally no way you're leaving your apartment—for fear of frostbite, or sheer laziness, we're cool with either—Co-Founder Vanessa Packer demonstrated ModelFit's signature small movements in her Soho apartment (with her faithful Dalmatian keeping close watch). So gather your hand weights and roll out your yoga mat. You've got absolutely no excuse not to.

Vanessa is using 2-lbs hand weights and 3-lbs ankle weights. She the Outdoor Voices Athena Crop Top, Sweaty Betty leggings, and Nike sneakers. Visit ModelFit for more. The Weekend Workout is a regular series at Into The Gloss, focused on bringing some of the most effective workouts into your living room, basement, or really anywhere else you like being active. Tune back in each week for new routines. Produced by Maya Margolina.
