"The facilities are incredible — the Technogym equipment alone is worth it. My trainer designed a program around my specific goals and I've seen more progress in 2 months here than in a year at my old gym."
"The spin classes are absolutely addictive. Anna and Ashley bring so much energy — I look forward to every session. The rooftop classes in summer are a whole experience. Nothing else like it in King City."
"Used ACE's rooftop for our company team day — the team at ACE made the whole thing seamless. 40 people, incredible views, and a really memorable experience. We're already planning the next one."
"First time on a reformer and I was nervous — Gunes gave me modifications for every move so I could keep up, and my heart rate was up the entire class. Left feeling strong, not defeated."
"Sarah's Power Pilates class is challenging in the best way. I couldn't finish every set, but I loved every exercise and I'm already booked in for next week."
"The studio is spotless every single time and there's plenty of equipment for everyone. Small classes mean the instructor actually corrects your form. Best Pilates in King City by a mile."
