I only wish I had found Fast Fit sooner! This is the best workout program I have ever done. Because of that, I am extra committed to making it work. It's most definitely the most consistent I have ever been with exercise or going to the gym.
One of the benefits is that I feel stronger almost immediately. I am noticing results, such as gaining muscle and having more appetite.
It is also so data driven and I love that it is rooted in science and data.
It's literally the best 20 minutes of my day most of the time because it's so easy to get in a workout and still not have it run my whole day.
The app is easy and scheduling has been extra convenient.
I have nothing but eternal high fives for Antonio, who has done such a good job of both motivating me to improve while celebrating successes, too. He is an excellent cheerleader and I always know I am safe on the equipment because he's so knowledgeable and attentive.
I have also been working out with an injury for a week or so, and they did such a good job of working around the issue spot by providing gentle support to that area. I still am able to workout my other muscle groups with no pain or detriment to the injured area.
I'd highly recommend Fast Fit, especially if you have tried other things that were frustrating. It is the most common sense exercise program I have ever done and I love it.
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.
