"After Burn"

Excess Post-Exercise O2 Consumption (EPOC)


"AIM Owners have been working out with EPOC/AfterBurn/MyZone® since 2012!"


What happens to your engine at the end of a long car trip? We all know this… it stays warm!

The same thing happens to your body after exercise. Once a workout is over and you’re back in your daily routine, your body’s metabolism can continue to burn more calories. This physiological effect is called excess post-exercise oxygen consumption, or EPOC. It has also been called “after burn” and is how your body can continue to burn calories after exercise is completed. Exercise that places a greater demand on the anaerobic energy pathways during the workout can increase the need for oxygen after the workout, thereby enhancing the EPOC effect. High-intensity interval training (HIIT) is the most effective way to stimulate the EPOC effect. The EPOC effect from a HIIT or high-intensity strength-training workout can add 6 to 15 percent of the total energy cost of the exercise session. EPOC is influenced by the intensity, not the duration of exercise. At AIM we can measure that intensity in REAL TIME by using MyZone.


Myzone® is an innovative wearable heart rate belt that uses wireless and cloud technology to accurately and conveniently monitor physical activity. The MZ-3 tracks your heart rate and is the equivalent of an EKG (99.4%), which shows and rewards effort when you work out. The belt displays real-time heart rate, calories, and intensity using five simple color-coded personalized zones. Your personalized MyZone® page/app can also keep track of your weight, body fat and muscle mass index when measured in the gym and uploaded to your site. MyZone® will also send you detailed workout information after each session.


The Gray zone at 50-59% is great for warm ups and cool downs. As intensity increases you will move up into the Blue, Green Yellow and Red zones. The last two zones, Yellow and Red, are achieved during high intensity exercise and these are the zones that experience EPOC or afterburn.


Strap on your MYZONE® belt prior to any physical activity inside or outside of AIM to track calories burned, heart rate, duration of activity, and more.



Wear your MYZONE® belt at AIM and see your exercise intensity in real time in the form of a color-coded tile that will show you how much effort you're exerting at that particular moment.



Pair your MYZONE® MZ-3 belt to the free MYZONE® app, which serves as your portable tile. You can stream your activity, upload your data, and review your results right from your smartphone. In addition, the app allows you to monitor your activity calendar, workout graphs, and challenges, as well as upload your before and after photos and keep a picture food diary.



Your personalized MYZONE® tile is full of helpful information to keep you working hard. It displays your name, calories burned, zone color, effort level, heart rate, and MYZONE® Effort Points (MEPs) earned.



The color of your tile represents the zone you're working in according to your effort level. MYZONE® Effort Points (MEPs) are awarded for every minute spent exercising in a particular zone. High zones indicate more effort, which translates into more MEPs. MEPS are a credible metric used to measure intensity based physical activity.
