Feel the burn with this upper body HIIT flow with dumbbells. Performing the workout in a circuit of four upper exercises, you'll flow through each exercise with little rest.

The focus of this dumbbell HIIT will be improving your muscular endurance, and then you'll move into a high-intensity (with low-impact options) series to get the heart rate up.

I had a ton of fun programming this workout and I hope you like it!
