I have a pair of gymnastic rings at home and attempted to learn doing pull-ups during the last 2 months. I did 3 workouts a week mainly just doing eccentrics. I also did some body rows as an additional pulling exercise. I got my first proper pull-up with chin over the bar (bottom part of the rings in my case) last week. I still don't get all the way up on every attempt, but sometimes.
Now I have developed a habit where whenever I walk past my rings I always go for an attempt of a single pull up. I tend to do this even on my rest days. Is this a bad habit? I'm just wondering because usually it is said that you want to rest your muscles between workouts, and considering I can only barely do the skill this must be close to a maximal effort for my muscles. Should I stay away from the rings outside of workouts?
As a small secondary question: Is it a good idea to keep doing sets of negatives during my workouts now that I can do the full movement? Or should I replace them with sets of single rep pull-ups?
