For fitness coach Jack Hanrahan, rebuilding the body isn’t just about performance—it’s about freedom. After suffering a debilitating knee injury at 16 and being told he’d never play sports again, Jack dedicated the next 15 years to understanding movement at the deepest level. Through his experience as a coach and educator, he’s helped thousands of clients eliminate pain, build strength, and reclaim their confidence through his holistic approach to training.

When it came time to take his proven Rebuild Training philosophy online, Jack knew the platform he used needed to match the quality of his fitness programs—and after years of frustration with unreliable software, he found his long-term solution in Movement.

What’s your business and who do you help?

I run Rebuild Training: a health and fitness coaching business designed to help people rebuild their bodies and achieve complete physical freedom.

Through my online training programs and 1:1 coaching, I help individuals overcome chronic aches and pains, get stronger, and move better so they can live without limitations.

"My approach combines strength, mobility, and conditioning—built on the philosophy of smarter training, superior results."

What led you to create an app?

For 3 years, my fitness app was hosted on a different platform, but constant frustrations forced us to find a better alternative. Building and managing exercise programs was immensely time-consuming and we needed a freelancer just to help with this task.

Feature requests to improve the workout experience were ignored and feature development was painfully slow. Payments were received months late. I could go on…

Why did you choose Movement to create your app?

After researching alternatives, Movement stood out. A great call with the founders led us to sign up for their 'Done For You' service, and soon we had a sleek new app that solved every issue we faced.

Would you recommend Movement to other fitness coaches?

Yes, I would recommend it. 

Since switching to Movement, Jack has built a stable, scalable, and beautifully designed fitness app that delivers the same world-class coaching experience he’s known for—without the technical frustrations that once held him back:

“My business is finally stable, scalable, and focused on what matters most—serving my clients.”

With the new Rebuild Training App, everything now lives in one place: structured programs, follow-along workouts, and in-depth education that help clients move, feel, and perform at their best. The result? More time for what matters most: serving his clients and helping them achieve complete physical freedom.

With Movement, he’s not just helping build stronger bodies but redefining what smarter training looks like online.
