I did it
At least 30 minutes a day, every day, for a 100 days
Today is day 101. The only requirement was/is a continuous 30 minutes of heart-rate-raised (so, walking my dog doesn't count). I'm mostly cycling in the gym though while watching TV shows on my phone. (I totally recommend doing that if you got a smartphone - have a TV series you really like and there are a couple of seasons of, and ONLY watch it when you're in the gym. That way, I ended up exercising longer, making it less boring, and actually looking forward to it more.)
I started this as a work-out-every-day-for-a-month challenge and then I just kept going. It wasn't always easy (especially those 2am workouts, or when I had particularly bad binge/purge days), but I really do realize more and more how good exercising is for me.
And, the most awesome thing: it's becoming routine! I thought that would have happened sooner, but it really only started feeling like a routine some 10 days ago or so. So it took 3 months! Before that, I would worry all day every day that I wouldn't do it, and that I would be a failure if I wouldn't, and it took me a lot of convicing-myself to actually go out and do it. So, rather high stress levels associated with it. Now, I'm more relaxed, and I don't _have_ to go work out right after I get home from work. If I'm hungry I can eat first, If I'm tired I can sleep first, and I'm confident that won't be the excuse to skip my workout. It's kind of hard to explain, but I did stress a lot
about whether I would go to the gym today or not and reminding myself that I should go. Now, not so much, and I'm loving it.
Now, the next step will be to stop fretting about when I will have my first day off, and then NOT feeling like a failure for breaking the chain. I've got a move coming up, and since the gym is part of my apartment complex, there may well be a day or two of missing workouts, although I still can go on rides on my ordinary bicycle, which I enjoy too. So, I hope there won't be any missed days, but .. I mean, eventually, there will be. I try to do it as long as I can without breaking my back, and then once I break the chain, I know it'll be alright. Because the chain isn't the point anyway, but what I wrote above - making it routine.
