Building Better Workouts Through Better Technology

Hey! I’m Steven Bell, the Founder and CEO of PROTECHT + CENTRIC.

CENTRIC was born from a simple frustration: why does gym technology focus on everything except the actual lifting?

As the founder of both CENTRIC and PROTECHT, I've spent years combining technology with serious training. During my own weight loss journey, I relied on my Apple Watch to track everything - heart rate, calories, steps, sleep. But when it came to the most important part of my workouts - the actual reps - I was on my own.

I watched lifters (including myself) rush through sets, let ego drive the weight selection, and miss out on the muscle-building benefits that come from controlled, intentional reps. Meanwhile, our wrists held incredibly sophisticated technology that could solve this problem.

CENTRIC represents our mission to bring meaningful innovation to the gym floor. Not flashy features or social media integration - just tools that make your workouts more effective. Whether it's our time under tension app or the Apple Watch-compatible lifting gear at PROTECHT, we're focused on using technology to build better lifters.

Every feature in CENTRIC comes from real gym experience. The bathroom break screen? Because we've all been there. The phase-by-phase breakdown? Because counting seconds while lifting heavy is impossible. The haptic feedback? Because your hands should be on the bar, not your phone.

We're not trying to reinvent fitness - we're just making it smarter, one rep at a time.

CENTRIC handles the timing, but the right gear makes all the difference.


Our smartwatch-compatible lifting gear at PROTECHT are designed by the same team that built CENTRIC - because we believe your entire workout should work as seamlessly as your technology.
