Meet Jake Derr

Experience You Can Trust. A Philosophy That Works.

Jake Derr has been helping people transform their bodies and mindsets since 1995 with a simple but powerful philosophy: train like an athlete.

Over the past three decades, he has worked with a wide range of clients — from competitive athletes to busy professionals — all with one goal in mind: helping them perform better, feel stronger, and move through life with confidence.

With a PhD in Exercise Science and advanced degrees in Sports Medicine and Clinical Nutrition, Jake’s approach is grounded in both science and real-world application. Every program is built around how your body actually works, taking into account your physiology, your goals, and your stage of life.

One of the first things clients discover is that age is not a limitation. With the right plan and guidance, strength, energy, and performance can improve at any stage — whether you’re in your 20s or your 70s.

What sets Jake apart is not just his knowledge, but his ability to simplify the process. From your very first conversation, you’ll walk away with clarity, direction, and confidence — knowing exactly what to do and how to move forward.
