Join the fabulous Jessi Lucatorto for 45 minutes of cardio-infused sculpting work. This workout will function more like a HIIT class (high intensity interval training), so you can expect to get your heart rate up, boost your metabolism, and keep your body from plateauing with this active flow.

Props needed:
* 8 lb. dumbbells
* 3 lb. dumbbells
* Water and a towel (*optional)
