The NASM certifications are recent, but there's a reason for that.
Around two decades ago, I worked as a personal trainer for several years during college — certified and training clients directly. After graduating, I moved into a career in engineering and let the certification lapse, since there was no longer a reason to maintain it. But while fitness was no longer a source of income, I never abandoned the love for helping others along their own fitness journeys.
That idea — building something like Sustainably Fit — stayed in the back of my mind for years. In my early 40s, with a stable career behind me, I realized I was finally in a position to turn it into reality. As the idea started to take real shape, getting re-certified became a necessary part of doing it right — including the CNC, which properly anchors the nutrition side of the system.
So while the certifications themselves are new, they are recent because this is the first time in decades they would serve a real purpose.
