The Perfect Workout has been my saviour this summer. I started 3 months ago, have lost over 13 inches, and have finally worked out regularly. I give it all I have, and feel sore for several days every time. Faith is truly awesome. She really knows her stuff, and is a huge help, and a great support! I highly recommend this gym!

How is FastFit different from traditional weightlifting or gym workouts?
Traditional workouts often require you to choose weights, which can lead to undertraining (read: less-than-optimal results) or injury. FastFit’s Adaptive Resistance™ technology adjusts resistance in real-time to match your strength, ensuring you get the most effective workout possible in less time.
What is Adaptive Resistance?
Adaptive Resistance™ technology uses patented, motorized resistance and computer software to give you the perfect workout every time. The system dynamically adjusts the resistance you receive, in real-time, to automatically provide precisely the right amount of resistance for every rep of every set.
This means you never have to choose weights or worry about miscalculations—our technology handles it all, so you can focus entirely on your performance.
