You're only four weeks away from a fitter, stronger you — and all you need to get there are some dumbbells and 30 minutes four days a week! The Get Fit Summer Challenge is a full-body strength and cardio workout plan created by NYC-based trainer Jessi Kneeland, NASM, of ReModel Fitness. Every week, you'll get four emails telling you exactly what exercises to do, plus tips on proper form. You'll feel more fit before you know it — and build habits that last a lot longer than summer.
