I can only confirm this and still struggle whenever I want to create a new habit. Russel Barkley when speaking about ADHD in children suggests to prefer productivity over quality. Want to work out more? Go for a walk/run every day, start and don't bother about the distance or duration. Same for the gym, as long as you keep going there, doing whatever you improve the likelyhood of doing it better this or the next time.
