Every couple years some new trend pops up that people start claiming will fix everyone's mental health issues. One of the current ones seems to be weight lifting. I have no doubt it can be massively helpful for mental health for a lot of people, but it's awfully condescending and detached from reality when people show up say "lmao drop therapy, all you have to do is pick up heavy things".

Does your statement apply to “get therapy” itself?

I’m not trying to be snarky, I’ve seen way more advices on getting therapy rather than start lifting weight. I don’t have an opinion one way or another, but when I read the GP advice, I thought it was the one being unusual rather than common

If the claim is "just go to therapy once a week and you'll be cured", then I would say yes. Depression is multi faceted and there's no single solution. It would likewise be ridiculous for somebody to say "stop weight lifting, all you need is therapy".
