Fitness trainers and entrepreneurs Taylor and Justin Norris guide us in a 20-minute low impact HIIT workout focusing your entire body, including both standard and modified versions of each exercise.This workout consists of a warm-up, toe taps, squats, lunges, inchworms and more—all movements you can do with no equipment right at home. Grab some water, a towel, a foam roller (if you have one) and get ready to sweat!
