Meet your Trainers

Strong As One is the creation of Diani Walker and Simba Rwambiwa, both collectively having over 20 years of experience as Track athletes, competing nationally and internationally respectively.

Having had access to world-class training and coaching to help their own athletic careers, the pair then decided they wanted to bring this tremendous experience to those who want to improve their overall fitness in a unique way.

Why Train With Us?

How we train our members is based on our own training, so we can safely say we know that it works!  We are sport specific which means that no workout is ever the same, that’s because we work on all areas of your fitness and you’ll probably discover muscles you never realised you had. You always hear an athlete say its 10% body and 90% mindset. Now…we are not training you to be the next Usain Bolt (unless requested), however, it’s those qualities we want to bring to every workout, so we won’t just push you physically but we’ll help channel a mindset that makes you determined to see and get results.
