Onboarding
Your goal, your training experience, the days you can train, and — the part most apps skip — the equipment you can actually reach. A short health screen runs at the same time.
HOW IT WORKS The loop
How Fynrox works: a plan that adjusts every week
Fynrox is not a library of workouts you browse. It is a loop: you tell it your goal and what equipment you actually have, it builds a plan, you log what you do, and a weekly check-in adjusts the plan from what you logged. Everything else on this site is a detail of that loop.
STEP BY STEP
What actually happens
Your plan
A structured program, not a random workout generator. Every exercise in it is one your equipment profile says you can do; anything it can't be done with has a substitute rather than a gap.
Train, fuel, recover
Log sets with weight, reps and RPE. Log meals and water. Check in daily on sleep, resting heart rate, HRV, soreness and energy. Each of these is a tab, not a buried screen.
Weekly check-in
Once a week Fynrox asks how the week went and compares it with what you logged. That is what changes next week's plan — not a slider you have to remember to move.
Ask the AI coach
Fynrox AI answers from your own logged data — your sets, your meals, your recovery trend. General fitness and wellness guidance only, and it says so when a question is outside that.
Add a human, if you want one
Request professional guidance and Fynrox matches you with a verified professional. You see exactly what they can see before anything is shared. How guidance works.
WHEN SOMETHING LOOKS WRONG
The loop has a brake.
If your health screen or a check-in raises something that shouldn't be trained through, Fynrox doesn't quietly carry on. Depending on what it is, you'll see a warning before the session or the plan is paused until you've spoken to a professional — and a heart condition always pauses it. That is a deliberate trade: an app that never interrupts you is an app that will eventually interrupt you far too late.
