About HYX

Built by hybrid athletes, for hybrid athletes.

We got tired of juggling three apps, ignoring conflicting data, and guessing whether we were recovered enough to train. So we built HYX — the one app that actually understands hybrid training.

Our mission

Make elite training science accessible to every hybrid athlete on earth.

The tools used by professional athletes and sports scientists have historically been locked behind expensive labs and coaching staff. HYX puts that same science — muscle strain modeling, recovery scoring, adaptive programming — in your pocket. Free.

What we believe

Science first

Every feature is grounded in exercise physiology. No bro-science, no guesswork — just what the research actually says.

Hybrid by design

We didn't bolt on endurance tracking as an afterthought. HYX was architected from day one for athletes who do both.

Simplicity over complexity

Data is only useful if you act on it. HYX turns complex physiology into clear, actionable guidance every day.

Free to access

Elite training science shouldn't be paywalled. Our core features are free forever — upgrade only if you want more.

The story

HYX started with a frustration shared by thousands of athletes: the best fitness apps are either built for powerlifters or for runners — never for people who do both.

Whoop tells you your recovery score, but it doesn't know you just did a 5×5 squat session that torched your quads. Garmin tracks your runs, but has no idea your upper body is fresh and ready to press. Generic apps treat all training as the same load on the same body.

We knew the solution was muscle-specific strain tracking — understanding not just that you trained hard, but which muscles you trained and when they're recovered enough to train again.

That's HYX. One app, built from the ground up for the athlete who refuses to choose between the barbell and the road.

Train smarter starting today.
