Heart Rate

All our workouts are designed for you to train above 81% of your max. heart rate.

Holistic

When you beat 81%, your body burns calories and fat to the max. Plus you build strong lean muscle.

Afterburn

Spending more than 15 min. above 81% unlocks the afterburn effect: You burn free extra calories!

Heart Rate Technology

See your progress

Our sensors will track your heart rate during workouts. Watch how your heart is responding to every squat, sit-up and sprint on the big screen in real-time. If you see that your heart rate drops, speed up your movements or increase the weight you’re using. Your goal is to stay above 81% of your max. heart rate for as long as possible during rounds and use the breaks to recover.

Take the challenge

Motivation in real-time

Get fitter minute after minute

Every minute you beat your personal 81 you earn one GritPoint. Push through the rounds and pocket as many GritPoints as possible. Can you beat your team mates? After our workout, you will receive a detailed report in our app. Track your results, see how many calories you’ve burnt and get ready for your next challenge.
