Welcome
I’m Preston Shamblen — ISSA Certified Personal Trainer, NCCPT Certified Personal Trainer, Certified Pool Operator, entrepreneur, outdoor enthusiast, creator of PrestonShamblen.com and the Rucking App!
After losing 90 pounds, quitting alcohol, and rebuilding my strength from the ground up, I committed my life to real-world fitness, building independent businesses, spending more time outdoors, and exposing the scams that most people ignore.
Here you’ll find everything I stand for:
- Real work that lasts
- Adventure and nature appreciation
- Building businesses with integrity
- Exposing frauds and financial lies
- Living free and moving forward
Whether I’m rucking through a state park, paddling in a clear kayak, building new projects, or calling out the phonies — I believe in doing things the hard way, because it’s the way that actually matters.

What I’m Building
Here’s a look at the businesses and projects I’m building from the ground up:
E-commerce for quality outdoor gear, tech accessories, and more — built with care, packed with pride.
Apparel, accessories, and attitude — expressing fun, excellence, and humor.
Crystal-clear kayaks built for adventure, exploration, and freedom on the water. (Coming soon! Tariffs 🙁 )
Family-run pool maintenance, service, and repairs — keeping West Texas pools clean and ready for summer.
Supplements and fitness gear that actually work — promoting real-world strength without the hype.
Rucking Calorie Calculator App and resources dedicated to real-world strength, endurance, and building grit through rucking.

Life without a computer wouldn’t change much for me—I already spend hours outdoors rucking and working in the Texas sun. The real difference is economic: computers help me connect, grow my pool business, and share projects like Rucking.pro. For me, the key isn’t abandoning technology, but finding balance between time outside and intentional time online.
