Might Be A Useful Article.

https://www.pea kendurancesport … eping-flexible/ in a search to understand collagen, this popped up, and it mentions mostly things that happened under tension to muscle but other tissues including collagen are mentioned. I’m not quite understanding it, but I think there’s helpful info here, if I just knew what the heck I was reading 😮

Thanks, it’s quite useful info.

Good read, didn’t know about the 4 hours. However, even though it takes only 4*20s to stretch to 95%, it’s the last 5% that seems to make the difference most PEers look for.
