Balance Fitness – Look for the indigo building at St. Clair and Yonge — that’s where you’ll find one of Sassy’s GTA faves. Balance Fitness is spotless, professional, and packed with top-tier instructors who actually know your name. Derek Friday is the Pilates pro to see; his sharp eye for form and fierce core work means even the fit folks feel the burn. Book a few privates with him before diving into reformer classes — your spine will thank you. Serious about Pilates? This spot delivers.
