About
I’m Will, an in-home personal trainer with 7 years of experience helping people build real-world strength, move without pain, and feel confident in their body every single day. I specialize in muscle building, mobility training, and PNF stretch therapy — a hands-on technique that unlocks flexibility most people thought they’d lost for good. Everything I do is built around one goal: making you capable and resilient for the demands of real life, not just the gym. Injury prevention isn’t an afterthought — it’s the foundation. I train clients where they’re most comfortable, in the privacy of their own home, with a program built specifically for them. Your first session is a free fitness assessment. No pressure, just clarity on where you are and where we’re going.
