  • Hi

    I’m about to start my first training session using Frontier X. I connected the device to Zwift which worked out well (it says ‘connected’), but there’s no information data transmitted (Zwift says ‘no signal’ and heart rate shown is 0, see attached screenshot).

      • I had long Covid for 14 months before considering a jab, with neurological cardiovascular misfires showing as ectopic beats. Took J&J on 5 June 2022 and they instantly stopped. Then two months later, they started up again. Covid itself can cause these problems. Correlation is definitely not causation. It is now 3 September 2022 – my first day with…Read More

  • Newbie question. I just recorded my first workout. A high intensity bike ride. Cardio strain registered -0.02 overall and was basically zero the whole time. Is that normal when working hard? Or do you reach levels like .15 or .2 only when on the brink of exhaustion? Otherwise, the ECG and pulse readings seemed fine…
