Possibly!
Some users in the forum here report that they prefer to do their endurance training below LTP - myself included at times. But there are probably times when it may be beneficial to train closer to LTP (like “Tempo” training), especially if that might be beneficial for the type of riding/event that you’re training for. If I have several days of low intensity in a row because I am yellow status from high-intensity training, then I often will include some “tempo” riding on one of those days. Not saying you have to do that, but it’s worked well for me.
On that note, this might be an interesting thread: All power values below TP contribute the same amount to XLSS?
