Canfitpro-certified personal trainer Heather Robertson knows you can get a good full body burn in just 20 minutes. One of the most effective ways to train is with AMRAP training, which stands for “as many reps as possible” and is a form of HIIT. For this workout, Robertson programmed four different circuits that include four different workout programs to perform eight reps each. Then continue performing these exercises for as many rounds as possible in the five-minute cycle followed by a rest. You get into a strength workout all over your body and get your heart rate up at the same time.

The exercises include jumping jacks, crunches throughout the body, deadlift and row, triceps press and more. You will need a pair of medium-sized dumbbells (here is a guide on how to choose the right weight). So clear some space, throw down a mat, and get to work!
