Unpopular opinion: Standing desks are overrated for freelance back care

I've been freelancing for five years and tried a pricey standing desk to help my back. Some friends swear by them, saying it stops pain from sitting all day. But I found that taking short walks often works just as well. On the other side, a pal invested in one and says it changed his daily routine, reducing his stiffness. For me, the cost didn't match the benefit. I think we might be buying into a trend without real need. What do you think? Have you seen a big difference with a standing desk, or is it just hype?
