That will possibly be demotivating, yes. However now that the habit has stuck with me and progress is more like weekly, I have integrated it into my identity. As in, I am the guy who always goes to the gym on these days and does these exercises. I am now someone who "goes to the gym". Once something is part of your identity, the ability to maintain it is surprisingly easy. For example some people have ingrained preferences that are identity-based, eg vegetarian, non-drinkers, non-smokers, non-soda drinkers, etc. It's easy for those people to avoid those things as it is part of their identity. Or habits that are part of someone's identity like "the person who always makes the coffee" or "the person who always takes the stairs". For you, it might just be "I'm a runner, so I run." I will also say that while it was never an initial goal of mine, the vanity/esteem aspect of feeling stronger/in better shape than others my age still is motivating.
