Next-Level Training

Afterburn is four weeks of High-Intensity Interval Training (HIIT) designed to rev up your metabolism, torch calories, burn fat, and build muscle. You'll go through bouts of intense activity, like sprints, followed by periods of less-intense active recovery or complete rest. The benefit of this HIIT workout is your body's ability to stay in fat-burning mode long after your workout is finished, known as the "Afterburn Effect." You'll leave with the satisfaction of completing an intense workout session, and will reap the rewards of the hour-long workout.

SkyPulse, with MyZone technology, works directly with Afterburn programming in each Sky facility. Myzone is an innovative wearable heart rate based system that uses wireless and cloud technology to accurately and conveniently monitor physical activity. 


MyZone monitors heart rate, calories, and time was exercising that convert into Myzone Effort Points (MEPs), with a focus on rewarding effort rather than fitness. Trainers can also help motivate you by viewing your percent effort. It is not required for participants to have a MyZone belt; however, their experience throughout the program is increasingly personalized due to the subjective nature of heart rate monitoring.


Afterburn participants receive a discount if they purchase a belt with the program.

A few "frequently asked questions"

AFTERBURN is a small group training program designed to allow everyone to train with the proven most highly effective fat loss and cardio improving style of exercise. This High-Intensity Interval Training (HIIT) program is developed to help you improve body composition, cardio endurance, and maximize calorie burn.

This program is for everyone. The interval aspect of the program can be adjusted by the trainer leading your group to fit your current level of fitness. That’s what is great about group training; everyone can work hard regardless of their fitness level. We do encourage you to let us know about any physical limitations you may have upfront; our trainers can adjust the exercises to fit your capabilities in most cases. If you’re still unsure if it’s right for you, schedule a Connect Session before you sign up to meet with one of our Private Trainers.

HIIT is a style of training that balances periods of high intensity(difficulty) with periods of low intensity for recovery, like sprinting & walking. Training with this method has been shown to improve cardio endurance, decrease body fat, and increase the strength and power output of muscles.
