I have learned a ton since training with the experts at FastFit; and I’m no stranger to the concept of Body by Science. The staff is exceptional, and being able to self-train is a huge plus, at least for me.

8.5/10. The facility is neat, quiet. Clientele are amicable and devoted toward frequent sessions.
Other than the occasional middle aged female screamers when I’m simply trying to get a puffing pump going (weird) this is a fine starter/intermediate gym. It is rather unfortunate that one would HAVE to be required to pay the full investment of a “Coach Guided workout” due to the fact that for a core maneuver of the tricep extensions has your back turned away from the performance screen to inspect one’s own effort-flying blind so to speak. Coaches are not required to give you pointers or corrections whatsoever when owning the bare bones “self guided” plan.

if youre able to, i really think its worth the investment not just as your primary strength training regimen but to compliment what youre already doing, even if you already strength train outside of the fastfit program -- excellent and personable trainers on site, the facility is small, comfortable, and very clean, and if you are a shoe hater like me, you can do the workout shoes off 👍
i also think the convenience of being in and out within half an hour is also really helpful especially for those who may be new to strength training or have a tendency to be indecisive when it comes to organizing or planning workouts, i definitely have notice improvements in my energy and strength since beginning and would encourage people to give it a try!

A full-body strength-training workout in 20 minutes! I have yet to understand the machines and all their metrics, but I am seeing significant improvement in my strength and tone, and Megan and Anne are great!
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.
