I think most of the time we overlap lack of scheduling/discipline with laziness (being a couch potato). I'm a disaster at scheduling things, unless they involve other people. But when it comes to putting in the effort and the hours to get something done before a deadline, man, you can bet it's gonna get done.
Similarly I've had periods of 3-4 months at a time where I was super disciplined about nutrition and exercise followed by a period of extreme disregard for anything related to my health. As in eating pizza 3-4 times a week. What I noticed is that it all starts with going to the gym 1-2 times and not interrupting the routine. A trip abroad, a week long illness, they all pretty much end any kind of virtuous cycle that was forming. Maybe the trick is just to be consistent for X time? I don't know.
Routine is definitely helpful for things involving habitual tasks (like going to the gym).
Humans are loss averse and at some point, breaking routine becomes taps into the loss aversion and there actually is a friction to not going to the gym.
I suppose when you're starting out to go to the gym you are averse to breaking your existing routine (which could be bingeing netflix every night after work)
