Any motivation and habit building strategies welcomed!
In terms of habit building, I've found that taking the time to really notice how I feel after a workout (more grounded, clearer head, more positive -- thanks, endorphins), makes for a pretty effective positive feedback loop.
Where my antidepressants only really create a "noticeable" difference depression-wise when I've missed a day and feel what it's like without them, exercise gives me an immediate noticeable payoff. Which is pretty awesome in itself.
In terms of motivation, reading studies, such as the ones you listed, can be helpful sometimes.
Otherwise, hearing success stories of others can be helpful too, so good on you for starting this thread :)
I can definitely say that since starting running as preparation for my surgery, my mood has definitely improved.
My best tips for getting into exercise would be:
-Make sure you are getting adequate nutrition to fuel your body.
-Pace yourself -- starting out all guns blazing is not going to translate into a sustainable habit. From experience, it has the opposite effect, and tends to lead to dissatisfaction and overall exhaustion.
-Keep an eye on black and white thinking (this is still something I'm working very hard on) -- I used to feel like my yoga practice would
only count if I did a full hour including all the flows that I had "planned" I should do.
Which meant that on "yoga days" where I wasn't able to do the full hour due to energy/time limitations, I felt like a) why bother?, or b) if I did manage 20/30/40 mins, it didn't feel like it counted anyway.
Whereas in (rational) reality, it absolutely did count.
-Listen to yourself and identify the types of exercise you do enjoy (for a given value of "enjoy", I'm very aware we're dealing with depression). You're way more likely to stick with something if you at least somewhat enjoy it.
-Also try to identify the time of day you find exercise easiest to do.
For me, it's the morning. That way I can get it done, shower, and then get on with my day.
Having to exercise in the middle of the day seems much harder to be motivated for, and in the evenings I'm much too tired.
-Rest days are just as important as exercise days!
-Having some way of keeping yourself accountable can be helpful too.
Actually getting out and running in the mornings is 90% of the time not my #1 thing I'd want to be doing, but I know I always feel better after.
