The only habit you need are the regular strength exercises, especially for the stability of the back muscles.

Please, please forget about the stretches or "ergonomics" if you don't excersise. It will not help you in the long run.

I've found no research that indicates static stretching does anything except increase your tolerance for static stretching, anyway. No reduction in injury, no increase in range of motion, no functional benefits. Do it if it feels good, otherwise don't feel obligated.

Exactly. And stretching may lead to the further injuries if your muscles are weak and can't support the safe movement during the full range of motion. Especially if you already have hypermobility.
