I just move my body a lot while working 9-5. cross-legged, backrest to the left, front or right, kneeling on the chair, loitering like a bored teen, perfect 90° angles - everything but hunched over. In 14 years of doing this I’ve never had any back problems, despite being morbidly obese and not going to the gym.
Hold one arm on your body and stretch the other one to your side. Now make your wrists/hands point forward. This is a meter.
