Program Changes and Conditioning HR Zones

Hello,

So I just finished up GS&C 1 gen 2 and was using the conditioning zones based off of lactate threshold. I have since moved on to Strength 2 where the heart rate zones are based off of max heart rate. Should I just run with the lactate ones or switch because these are very different ranges. I can see some pros and cons for both e.g. the lower intensity being better for recovery for strength training but also that it wouldn’t be training conditioning as hard.

I’d use the HR zones in strength 2 in order to err on the side of less fatigue and lower training load from conditioning.
