Power v cadence

Hi need some help .During workouts i can’t achieve whats asked .If i ride at cadence it says more power and if i ride on the power shown it tells me spin less .I never get both together usually if cadence is perfect im getting power jumping up and down quite significantly.What im i doing wrong

You aren’t doing anything wrong, you just have to keep cadence around the recommended level and power around the target level.

If you are off slightly it’s not a problem. You’ll always be slightly above or below.

We can’t see exactly how much your power is varying by, but it sounds like normal when starting an interval for your power to take time to adjust.

Which trainer do you have?
