Upstream Fitness
Fitness That Fits. Movement That Lasts.
My name is Nathan Kennedy, and I’m the founder of Upstream—a fitness community dedicated to serving individuals of all ages, abilities, and experience levels. At Upstream, our mission is to break down barriers and make fitness accessible to everyone, especially those often overlooked in traditional fitness spaces—including individuals with autism, Down syndrome, and older adults. But our commitment doesn’t stop there. We welcome anyone ready to take a step toward better health and personal growth.
We believe movement is more than just exercise—it’s a pathway to confidence, connection, and community. Our flexible, personalized approach meets you exactly where you are, empowering you to achieve meaningful victories—whether it’s your first step or your next milestone. Every movement forward is an investment in a stronger, more inclusive future—for individuals, families, and the communities we serve.
