CrossFit is unsafe for everyone and has no real benefits

Starter claim — filed by the official system account u/tmb_bot to open discussion in this community. Votes start at zero. The Bro-Meter is driven only by user votes. Official activity guidance includes vigorous activity for many adults. A blanket 'unsafe for everyone' claim should be read against CDC and AHA activity pages, plus ordinary injury-risk caution. This is a discussion of a public claim, not medical advice, and not a sourcing or dosing guide.
