F45 San Dimas

Get ready to feel the energy the moment you walk in. Every F45 workout at F45 San Dimas fuses high-intensity interval training (HIIT), circuit training, and functional movement into 45 fast, electric minutes. Our F45TV screens guide you through each exercise in real time, so you always know what’s coming next. With thousands of possible movements in rotation, no two workout classes feel the same.

Every class is led by certified personal trainers who bring serious energy – and serious expertise – to every session. They’ll be watching your form, calling your name, and pushing you just enough to help you discover what you’re capable of – whether it’s your first functional training class or your 500th. Show up, and let them do what they do best: turn intensity into results.

You’ll train shoulder-to-shoulder with members who celebrate your last rep as loud as their own. It’s a no-judgment, no-ego, all-energy environment built on real community – where it’s our people who set us apart. Whether you’re trying a cardio, hybrid, or strength class, you’ll feel the difference from day one. Because this is more than a workout – it’s team training designed to bring out your best.

Want to walk in with a head start? Before your first class at F45 San Dimas, you may be able to complete a quick, non-invasive InBody scan to better understand your body composition. It’s an easy, eye-opening way to set your baseline, track your progress, and see how far you’ve come over time – and turn every gain, every milestone, and every personal record into more motivation for your fitness journey. Available at select studios.
