For busy people who love their workouts! This challenge is a carefully crafted combination of strength training and high intensity interval training (HIIT), and you'll be able to get your whole workout - including warm up and cool down - fully complete in around 30 minutes. These workouts are short, but intense, though low impact or intermediate options are shown throughout the videos. All you need is dumbbells.

What to Expect: Week One focuses on intense total body strength workouts with highly active cardio recovery days, while Week Two utilizes upper and lower body strength splits and a challenging HIIT workout.
