I’ve been training for awhile but after reading a new article about commitment vs discipline i could probably use more of both….. hence my questions.

1st some background:
ever since i’ve started working again after being unemployed for a year i’ve only been averaging 3hrs a week which i know isn’t going to get me to with in the magic 10% for a very long time if not at all….. ever since i started this journey i’ve been going out and running below my AeT for at least 50min at the low end, typically it’s an hour to 1 hr 10min, when i was unemployed it was regularly 1.5 to 2hrs at a time getting in closer to 4-5hrs a week. when i say below AeT it’s been typically in Z2 for example my AeT is 155, so i typically have been running at 150 or 140-145. my data is loaded up to TP and Runaalyze and I get a TRIMP and Pa:Hr or a rTSS and Pa:Hr depending on what i’m looking at.

so….honestly i have no real idea what TRIMP or rTSS really means or what I should be paying attention to and the little I know about Pa:Hr is for doing a AeT but beyond that not sure how it plays into training runs….. i guess my questions are:
1) if i really want to get to the magic 10% how many hours do i really need to put in a week?
2) should i spend more time in Z1 or what % between Z1 and Z2 should I be doing?
3) What does TRIMP/rTSS and Pa:Hr really mean in terms of training?
4) should i be paying attention to TRIMP/rTSS and how is that affecting me? same with Pa:Hr?
