  1. 1 Nothing reaches a client until you approve.

    Review what Fen pulled from each check-in, change a word, or send it with one press.

    Fenlio shows you exactly what it will do before it does it. Nothing is ever posted publicly, and nothing is sent from your account until you press Send.

  2. 2 Your whole roster, in one table.

    Who is waiting on a reply, who is going quiet and which clients are at risk, each with the reason.

Every weight, date and figure Fen writes is checked against the client's own words, and a load or macro target is computed from your rules. One with no source is flagged, never guessed.

Maya's check-in, 13 Oct

Example

“Got 4 sessions in this week and hit 120 kg for 3 on deadlift. Away for work in Denver from Thursday, hotel gym only.”

Reply to Maya

Email to Maya. Written by Fen from Maya's words, 13 Oct.

Great week. 4 sessions and 120 kg for 3 on deadlift is real progress. For Denver, I'll set Thursday up as a hotel gym session so the week still counts.

Got clients racing Hyrox?

Fen knows race day. Every client's training phase counts down to it, station benchmarks are tracked per client, and the taper window is worked out for you.

  • Race-date-driven training phases
  • 8-station benchmark tracking per client
  • Automatic taper timing

No client should go quiet because their coach got busy.

Find your client ceiling.

Most coaches plateau between 30 and 50 clients. Source

For example: two quiet clients a month at $200 each is $400 a month walking out the door.

We're new.

We're onboarding our first coaches personally.

  • White-glove setup

    We bring your clients, programs and method in with you.

  • A direct line to the founder

    Questions and requests go straight to the person building Fenlio.

  • Founding pricing, locked

    The price you join at is the price you keep, for as long as you stay.

Questions

Does Fenlio message my clients on its own?
Not at default settings. Every reply and nudge waits for your OK, and email goes out from your own Gmail.
Can my clients keep messaging me where they already do?
Yes. WhatsApp Business number, Instagram account or Facebook Page are coming soon. Each message lands on that client's record.
Will it write training programs?
From your own templates and exercise library. It never invents an exercise, a load or a number.
Is each client's information kept separate?
Yes. Each client's record is walled off from every other client's at the database level.

Your clients deserve your best judgment.
