I’m a massive fan of compacting my cardio sessions to be short bursts of high intensity. I can’t get behind spending hours on a treadmill or bike because it just doesn’t have the same fat melting, heart pumping effect that high intensity work does. Not to mention, who has a couple hours to spare AFTER they have lifted weights or been to work? This workout from Joanna Hall (Fitness Central) tics all my boxes when it comes to cardio; intense, can be done anywhere, works for any level of fitness, and only 5 minutes! So give this five-minute cardio burner a try and see the great workout you can get in just a few spare moments.
