If you didn't already know, I'm kind of obsessed with super efficient workouts. That means getting as much calorie burning, butt busting, muscle building as possible in a short amount of time. Because, guurrlll, I have an hour or less to fit in a good sweat, and I like to make it count! Who's with me? That's why all of the workouts in the Life in Spandex Sweat Guide are 45-minutes or less and can be done from anywhere. 🙂 I'm also obsessed with training my bootay! This 20-30 minute Shapely Legs & Booty No Equipment HIIT Workout deserves a round of applause because: 1) It's less than 30-minutes long. 2) It can be done nearly anywhere - hello sunny
