Yes. FastFit uses isokinetic resistance training to make every rep count, so your muscles are fully challenged in a short amount of time. That’s why just two 20-minute sessions per week provide the right balance of stimulus and recovery to drive real, sustainable results.
How is FastFit different from traditional weightlifting or gym workouts?
Traditional workouts rely on selecting weights, which can lead to undertraining or increased risk of injury. FastFit uses isokinetic resistance training, where the machine controls the speed of movement—so your muscles stay fully engaged from start to finish. This creates a more efficient, effective workout in less time.
Is FastFit safe for beginners?
Absolutely. FastFit is designed to be safe and approachable for all fitness levels. Our isokinetic machines provide smooth, controlled movement, and our certified coaches guide your form every step of the way—helping reduce injury risk while building confidence.
What kind of results can I expect with FastFit?
Results vary, but FastFit helps members build strength, lose fat, and improve overall health. Because workouts are designed to be highly efficient, members often see meaningful progress in less time. In a recent study, participants lost 2.5x more fat, gained 2x more lean muscle, and improved cardiovascular performance 3.5x more than traditional weightlifting over 12 weeks. Many also notice increased energy and strength within just a few weeks.
