Curlers getting in shape

Here is a link to today's Globe column. It's on the fitness levels of the curlers.
I've been impressed with how hard the curlers are working at this and of course Dean Gemmell's book with John Morris, Fit To Curl, is proof that this isn't just a flash in the pan.
I sort of liken it to when Tiger Woods came into golf and sent everyone running for their personal trainers. Can you play good golf without being in great shape? Sure, but you can play even better if you are. Same thing, it seems, is going on in curling.
