On Day 3, it’s time to give your muscles a little break and do cardio to burn off some fats. The best and most effective cardio workout is running. Not jogging, not walking at a fast pace. Running.
Run for 25 minutes, either outdoors or on the treadmill (speed should be between 7.5 or higher). Keep your heart rate up, try breathing deeply as you go and try not to slow down!
*Personal note: On my cardio day, sometimes I like to switch it up a bit by using the treadmill for 15 minutes, cycle for 10 minutes and row for another 10 minutes.
