I started with tubo trainers and zwift recently and I noticed that during Zwift workout my HR is extremely low and also the perceived effort doesn’t match the power readings. I dont have power meter on my bike, but if I look on let’s say 6% grade climb outside, going full gas, estimated power in Strava is around 250-300W with heart rate around 160-170bpm. When doing the workout with target power of 250W, the perceived effort is much lower and I barely hit 130 bpm heart rate.
Today I ride sweetspot and FTP intervals (90-100% FTP) workout and my heart stays in recovery and endurance zone the whole time (average117, max 136 -I should be again around 160-165)
Or compare this Zwift workout ride (https://www.strava.com/activities/558355815) with this outside ride (https://www.strava.com/activities/555328113) I know outside there is wind and stuff, but the perceived efforts are realle too different.
When riding free in zwift the heart rate looks normal and subjectively it seems much harder. So there should be anything wrong with heart rate monitor. Could there be something wrong with workout mode?
I use Tacx Genius Smart, Garmin Cadence Sensor and Garmin Heart rate strap.
Thanks in advance for your advise!
