A streak strikes me as a very different thing than a habit. Habits aren't hard to pick up after a break, streaks are. I have a hard time to figure out what it means for someone to "purposefully break a habit", except in the context of bad habits of course (eg a smoker trying to not smoke for a day). This is my whole point I guess, if you manage to make exercise a habit and not a streak (by making it fun, and feeling good, and having space for it in the daily calendar), then you can stop worrying about 0 days altogether and just do it every day except when you don't.
