HR Zone 1 vs HR Zone 2?

When riding my trainer, I often have a difficult time getting my HR to rise into Zone 2 – typically it stays about 8-10 beats per minute below Zone 2.

Just curious, am I still getting the aerobic base I would in Zone 2?

Thanks for the help!

Just guessing but did you set these zones outside? I find a notable difference in HR response inside versus out. Zone 1 should feel pretty darn easy so it shouldn’t be hard to get out of this area if you try. Sounds to me like your zones are off.
