Two dumbbells, six moves and 20 minutes are all you need to boost your metabolism and build muscle tone

Traditional strength training can sometimes feel a little dull. Repeat this one movement 10 times, do nothing for a minute, then do it all over again. It's effective, but the time can drag, so it was refreshing to see this fast-paced dumbbell workout from NASM-certified trainer Fernanda Shaw.

This workout targets muscles across your body, including your glutes, quads, shoulders, back and core. Shaw is moving quickly too so it's sure to get your heart rate high for extra cardio benefits. If you only have 20 minutes to move, this session is hard to beat.
