The problem

Fixed plans break.
Real coaches cost a fortune.

Today

Garmin Coach hands you a rigid plan that never changes when life does. A human coach is €150+/month and can't watch your sleep every night. So you wing it, plateau, or burn out.

With Custom Gains

An AI coach you actually talk to. It builds your week across any sport, adapts to what you really did and how recovered you are, and pushes every session to the watch already on your wrist.

How it works

Three steps. Then just train.

01

Tell your coach

Chat your goal, your sports, and how many days you can train. No forms — a real conversation.

02

Get your week

An adaptive plan appears on your Garmin, structured and ready. It rebuilds as your data comes in.

03

Adapt & improve

Bad sleep? Missed a run? The coach adjusts — no guilt, no streak shame. Just the next right session.

What you get

Built for every athlete.

Multi-sport

Running, strength, cycling, swimming, yoga — one coach across all of it, not a single-sport app.

On your watch

Structured workouts sync to Garmin and follow you on the run, in the gym, on the bike.

Recovery-aware

Reads your completed sessions and readiness, and dials volume up or down accordingly.

Conversational

Ask anything, change anything. "Move long run to Sunday." Done.

Honest data

Readiness, load, progress — the numbers that matter, never vanity metrics.

No bro-science

A supportive expert that backs every call with your data. No hype, no guilt.

Why trust it

Built by an athlete,
tested by real ones.

Why it exists

Garmin Coach kept handing me hard runs the day after I lifted, blind to half my training. So I built the coach I wanted, one that sees every sport, reads your recovery, and actually adapts. We ship fixes from beta feedback every week.

Taavi, founder

Real beta, real plans

One early athlete used Custom Gains to build a taper between a 135 km race and a 315 km ride in the same week. Five sessions, pushed straight to his Garmin, all adjusted by chat as his legs changed. That is the whole idea: a plan that moves with you.

Questions

Good to know.

Which Garmin devices work?

Any Garmin that supports structured workouts via Garmin Connect — most modern watches and bike computers. You link your Garmin once and sessions sync automatically.

What sports does it cover?

Running, strength, cycling, swimming, yoga and more — from day one. Tell the coach what you do and it builds for it.

Is this a fixed plan like Garmin Coach?

No. It's a conversation. Your plan rebuilds around what you actually did and how recovered you are — that's the whole point.

Do I need a Garmin?

It's built around Garmin sync. If you don't have one yet, you can still get the plan and follow it manually — native sync just makes it effortless.
