The Pandemic has changed many things including the way we exercise. There are no more packed gyms or crowded yoga studios. For now, we are not doing Barry’s Bootcamp, Orange Theory, and the SoulCycle in a small room with 20 other people. Our workouts have moved outside or changed completely. We have bought Peloton bikes, treadmills and home gym equipment. We have tried new types of workouts. As we start the new year, we were curious to see what research has to say about HIIT (High-Intensity Interval Training) workouts compared to lower intensity exercise.
