Meet The Founder

Hi, I'm Will Duru

I’m a personal trainer based in London and the founder of the 12REPS fitness app. Over the last decade, I’ve worked with hundreds of clients, helping them achieve greater strength, improved health, and reach goals they never thought possible.

The idea for 12REPS came from a simple observation I made repeatedly in the gym: people showing up without a plan. They’d wander from machine to machine, do a few random exercises, and leave feeling frustrated and seeing no real results.

My passion for fitness has always been a huge part of my life, driving me to study Sport & Exercise Science and learn the principles behind practical training.

User Reviews

What Our Users Are Saying

Based on App Store & Google Play reviews

"I've tried countless fitness apps, and honestly, most of them just dump a bunch of random exercises on you with no real structure. 12REPS is on a whole different level. From the moment I started using it, I could tell it was designed by real personal trainers who get it."
James R.
App Store Review
"The 12REPS app is by far the most comprehensive fitness app that I have used. It has detailed workout plans that can help anyone from the novice to the seasoned gym goer. The interactive body diagram and detailed workout videos allow you to tailor your workout with precision."
Sophie T.
App Store Review
"The personalised plans are spot on – it builds workouts around the equipment I actually have at home, which means no more frustration or skipping exercises. The demo videos and pro tips make it feel like I've got a PT in my pocket 24/7. No more guesswork!"
