here's an article recently published by the Toronto Star. It talks about weight lifters and how lifting affects their health.
Personally, I think it's a load of crud. They don't have much to back up their words, and the article seems to be very vague.
It's interesting to read some of the people's comments at the bottom of the page too!
Personally, since I've started lifting, I've become healthier, fit, calmer, relaxed, stronger. I don't know where people get these ideas from.
