I think Ric is okay. His field is bloody huge and every six months a new study comes out that tells you everything you believe is wrong, so no wonder things get out of hand.
As I understand it, there's slow twitch and fast twitch muscles, and if you're an endurance athlete, power work like doing squats etc is pointless. 'Endurance' by definition is not a short-term power requirement, it's a long term, low to medium sustained power requirement. As far as I see it, people who are obsessed with weights and the gym are just tossers anyway, in it for bragging rights - the real benefit is so they can say how much they can squat/press whatever. They probably bleach their teeth and use spray on tan as well
The best comment I've heard in regards to this sort of stuff is "The best training for cycling is riding ya farken bike". Words to live by. Probably no consolation if you're snowed in for 4 months of the year though, like half the Northern Hemisphere is.
Also no consolation when you have no time to ride coz you're too busy busting ya nads at work trying to afford that set of Lightweight wheels.
