The name says it all—this is a big, loud gym, full of beautiful bodies and even better-looking equipment. Extreme Fitness took over the location from Bally’s last summer and is currently pumping $3 million into it, two-thirds of which will go toward adding new locker room and lounge facilities (complete with leather couches, plasma TVs and a juice bar); the rest is earmarked for upgrading equipment (personal LCD TVs on every cardio machine, a new hot-yoga studio). These renos won’t be complete until summer ’08, but in the meantime, fitness buffs can enjoy the vast bank of treadmills and elliptical machines that offers a bird’s-eye view of Bay and Bloor, or the entire airy room full of Life Fitness strength machines. Each new membership includes a free fitness consultation; personal training can be financed.
