I built an AI fitness coach because generic plans kept failing me
I’ve spent the last few months building Apex Pulse PRO on my own.
The idea started from something simple: most workout and nutrition plans look personal, but they are usually written for an imaginary average person.
They do not really know whether you train at home or in a gym, whether you slept badly, whether your shoulder hurts, or whether you already told the system not to include a certain exercise.
That became the hardest part of building the product.
Generating a workout is easy. Making the coach remember the details that actually matter when someone asks for a different workout or a harder version is much harder.
I recently fixed a case where an explicit shoulder limitation had to remain active across follow-up requests. I also changed the app so it no longer shows personalized recovery values before the user has completed their profile.
The product is still evolving, and I am building it alone from Bulgaria.
I would genuinely value feedback on the first experience:
Does the onboarding feel worth it once you see the plan?
And what would make you trust an AI fitness coach enough to use it more than once?
