About David

I'm a certified personal trainer and sports and deep tissue massage therapist, with 15 years of coaching experience.

I have a passion for helping people get results and seeing their confidence come back. Over the years I've built a close community of clients, and many of them have become really good friends.

Three and a half years ago I opened my own gym, Boost Fitness. As life took some of my clients to new cities and new countries, my community grew with them. They didn't want to stop training, and I didn't want to stop coaching them, so I built the Boost Fitness app.

Now I coach them wherever they are, and anyone else who wants to join us.

Why we train

We don't train just to look a certain way.

We train so we can use the bodies we've built, and keep doing the things we love for years to come.
