The results do speak for themselves, but without the knowledge, enthusiasm, and motivation of The Smart Fit Method trainers, the experience wouldn't be nearly as uplifting and satisfying. The Smart Fit Method is revolutionary and whether you just do their program or supplement it in addition to other physical activity, I highly recommend it. Thank you, Smart Fit Method — You have changed my life!!! and now my wife of 43 years is hooked!!!

I feel fitter, stronger, and have more energy. This program has freed up time, which gives me more time to do other things like golf and yoga and spend more time with family. Joining Smart Fit has given me a solid foundation to ensure I will stay fit and maintain results. The additional support and advice on nutrition is an overlay that lends to a complete fitness and health program. The staff are really awesome. They are fun, knowledgeable, and really committed to your success.

Being able to track my progress is super motivating. I love feeling energized to go hard every week. Gaining a new understanding of my body and all the different muscles groups has helped me find alignment in my life. I'm able to be a fun, fit dad and make time for what I enjoy most in life. My coaches always give me a hands-on session and something new to think about, week after week.

I thought I was in pretty good shape when I started The Smart Fit Method. I was able to ride my mountain bike 20 miles in 2.5 hrs. 6 weeks after starting my training program at Smart Fit, I was able to do the same 20-mi ride in 2 hours, feeling much stronger at the end of the ride. I was sleeping better, my blood pressure improved, and my libido was like it was when I was in my 30s. This may be explained by a 3.5-fold increase in my measured testosterone level from a year ago.

I love the efficiency and tracking abilities of the program. The time efficiency is why I've been able to STICK WITH IT for this long. I love being able to squeeze it in when work and life get busy. The impact of joining Smart Fit has been profound and immeasurable in terms of overall well being. Although the technology and efficiency of the workouts are amazing, it's the personable, community feeling in the studio that makes it really special.
