I’m Will Duru, a personal trainer based in London and the founder of 12REPS, a strength training app built on a decade of coaching experience and a straightforward philosophy: everyone deserves access to expert programming, not guesswork.
Over the last ten years, I’ve worked with hundreds of clients — from complete beginners stepping into a gym for the first time to experienced lifters chasing new personal bests. What ties them all together is the same thing: they got stronger, moved better, and achieved results they didn’t think were within reach. Not because of complicated methods or trendy protocols, but because they followed a structured, progressive plan designed by someone who knows what works.
The idea for 12REPS came from watching the same scene play out in gyms across London: people showing up with motivation but no direction. They’d drift from machine to machine, pick a few exercises at random, and leave feeling like they’d wasted their time. No plan. No progression. No results.
