Dumbbell HIIT Workout app for iPhone and iPad

HIIT training on its own has amazing benefits. When combined with weights it gives a whole new dimension to your workout, allowing you to work your full body in a short period of time. HIIT with weights can burn fat and calories both during and after the workout, build muscle, and improve heart health. High-intensity interval training offers a highly effective (and highly sweaty) fast track to fat loss. Combining them is one of the most effective ways to maximize fat burn and improve heart health. And its ideal for beginners.
