An interesting article...

https://www.dailymail.co.uk/health/article-3370950/Are-sit-ups-BAD-Exercise-outdated-key-cause-lower-injury-replaced-plank.html#:~:text=An%20editorial%20in%20Navy%20Times,ups%20to%20be%20banned%20completely.&text=It%20called%20them%20an%20'outdated,cause%20of%20lower%20back%20injuries'.

hey guys! so recently, I came across this article on how bad sit ups (crunches) are. In fact, apparently the military banned them. Now, I'm not too sure about this which is why I started this discussion, so if anyone has any insight, it will be highly appreciated :)
