The state of your body changes every day, so the intensity of your training should change with it. The RCX5 listens to your heart and automatically adjusts your heart rate zones for that session.
To match your current physiological condition, your zones can be set higher or lower. So whether you’re swimming, riding or running – you’re getting the most out of every session, every time.
