Almost all of our workouts are based on approximation. For example a 125-lb person burns approx. 360 calories per hour if they do a vigorous dumbbell workout session. To remove the veil of doubt and talk about hard facts and figures, we have here the C-Ring Dumbbells. The weights sync with your smartphone or PC via USB and tell you exactly how many calories you burnt during your session. Color-coded lighting system displays how intense your workout is and if you could afford to step it up a notch. If you cant quite feel the burn just attach the magnetic weights to the dumbbell and feel your muscles ache with satisfaction! Best of both worlds here… Brains and Brawn.
