The benefits of working with challenging weights are immense: you’ll shape and firm your body, and speed up your metabolism, so you burn extra calories long after your workout is over.
You don’t need fancy equipment or even a gym membership, you can get a fantastic fat-torching workout at home with just a pair of dumbbells. I’ve created this circuit to fire up multiple muscles – more muscles working together means more fat burning, greater cardiovascular benefits, and better body-sculpting bang for your buck.
