f you are looking to mix up your at-home workouts and have minimal, or no, equipment, this is a great workout. I will walk you through the movements and a review of the workouts. This is an AMRAP ("As Many Rounds As Possible) HIIT. Set a timer for as little as 12 minutes or as long as 20 minutes. The movements are Squats, Pushups and Sit-ups (or Crunches). Follow the video to see how to scale these movements if need. Here's the workout: Start with 3 reps of each movement, then every round increase by 3 until the time as lapsed (3-6-9-12-15 and so on). The wheels come off the bus quickly on this one. Pace yourself, take mini-breaks where you need. to. Have fun!
