Calibration of the machine

[vya-34]

Good afternoon.I ran into a problem-I can't calibrate the machine.After warming up for 10 minutes, the P1 test asks you to accelerate to 20 km/h.But I can't do it.and the second p2 test is even more difficult.I feel like I'm going uphill.It's hard for me and I can't do it.What should I do?training in zwift shows the wrong power and i somehow need to make a calibration.I'm very upset about it.thank you, i hope for your help.
