After a warm up, begin on 4 mph at 5% incline, briskly walking for 5 minutes. Pump it up for the next 3 minutes by running on 6 mph at 2% incline and then at a 7 for 1 minute. Finish strong on a 10% incline walking at 3 mph for 1 more minute. Repeat this cycle for a total of 5 rounds and finish with a few minute cool down. Then reward yourself because you burned about 500 calories! Woot!
