Nathan's story
I've played sports since the second grade, but I didn't start lifting seriously until I was 29. Now, at 45, I've spent more than 16 years learning what actually works: training alongside a friend who coached for a living, learning from bodybuilding coaches and trainers with very different styles, and testing everything on myself first. All that trial and error led me to earn my ISSA personal trainer certification and study nutrition formally. Co-owning a medical spa with my wife, a nurse practitioner, taught me even more about how the body responds to training, recovery and food. HydroFitness is everything I've learned, built into one app: structured programs, real nutrition tracking, and a coach who's actually paying attention.
