Visualize a high intensity cardio interval training session. There's no time to think or second guess yourself, you are moving from the start. We want to take you to a place called EPOC (Excessive Post-Workout Oxygen Consumption). If you can reach and maintain at least 80% of your max heart rate for 20-30 minutes, you can continue to burn calories and fat for 24 hours after your workout. Looking to cut or trim some fat? This is where you put the cherry on that.
