No, heart rate sensors and chest straps are supplied free of charge to wear during every workout. The body stats you provide when you sign up (height, weight, age, gender) are used to ensure each sensor gets personalized to track your heart rate accurately, calories burned and GritPoints collected.

Please return the sensor and strap after your workout in the provided boxes. 

If you prefer to use your own strap you certainly can. Own sensors cannot be connected to our System.

All sensors and straps are cleaned after every session.
