I work out at Pape / Danforth ... a bit more "raw" but I like it more than the "oh I need all these 5 pieces of equipment for the next hour" mentality I keep seeing at Dundas Square. It's really frustrating trying to work around the obsessive folks around the free weights there.
However I've heard from other folks who workout there that it isn't so bad if you work out later in the evening.
Last time I was at Dundas Sq, I bitched to my workout partner about a (significantly larger) guy for using a bench as nothing more than his water bottle shelf, as he worked out in front of the mirror about 20 feet away. His towel was hanging off the weight rack. How much space did he actually need? He told me to fuck off. What an ass. I removed his water bottle, and after a few threats from him, and me faking complete obliviousness to his shitheadedness, he grabbed his water and left it on the floor nearer to him in front of the mirror, where he could admire himself some more. There he was out of the way of everybody, and somehow I didn't get hurt lol
All the eXtreme Fitness sites seem to be totally different. The Bay / Bloor one sure is cruisey, which can be fun, and truly great for the ego, after a hard workout.
