always be a CF Warrior
I know firsthand how hard it can be to live with CF and other health challenges. That’s why I built this space—to share the tools, strategies, and mindset shifts that helped me not just survive, but thrive. Here you’ll find clear guidance, encouragement, and real-life solutions to help you take control of your health and your life.
Hi, I'm
Tim Sweeney
I am a proud father of three, a double lung and kidney transplant survivor, NYC Marathon finisher, bodybuilding champion, author, certified personal trainer and nutrition counselor for over 25 years and 50,000 client hours—and above all, a relentless CF Warrior.
I have faced the impossible and turned it into fuel. I don’t just talk about resilience—I live it every single day. I know the grit, the mindset, and the unwavering determination it takes to fight for your health and live life on your terms.
Now, I'm on a mission to inspire and teach others with cystic fibrosis to rise, push limits, and redefine what’s possible. This is what it means to be a CF Warrior.
how can I help you?

FREE GUIDE: train on your worst days
Because CF doesn’t care what was on your calendar. And your plan shouldn’t fall apart when energy does. Some days, your lungs feel heavy. Your body feels slow. Motivation is low.

This free guide shows you exactly how to train when you feel at your worst — without overdoing it, without guilt, and without breaking momentum.
