Your body talks.
Your coach listens.

StrainCoach reads your Whoop and Garmin data every morning and rewrites your training plan. Not next week. Today. Because your body doesn't follow a spreadsheet.

Plan adapted: Swapped your 5x1km threshold intervals for a 45min Zone 2 run. Your HRV is 22% below baseline and you slept under 6 hours. Protect the long run on Saturday.

The problem

Generic programs don't know you
slept four hours last night

Online training programs hand you a 12-week plan and wish you luck. They don't know you pulled an all-nighter at work, your kid was up sick, or your HRV just cratered. You follow the plan anyway, and you either overtrain or undertrain.

01

Static plans, dynamic bodies

Your physiology changes every single day. Your training should too. Following Tuesday's prescribed intervals when your body is screaming for recovery is how injuries happen.

02

Data without decisions

You own a Whoop. You check your HRV every morning. Then you open your training plan and it says the same thing regardless. The data exists. Nobody's using it.

03

Coaches cost $300/month

A good human coach reads your metrics and adjusts your plan. But they're expensive, they have 20 other athletes, and they're not awake at 5am when you need to know what to train.

How it works

Wake up. Check StrainCoach.
Train what your body can handle today.

Every morning, StrainCoach pulls your overnight biometrics and recalculates your training. No manual input. No guesswork.

01

Sync overnight data

Whoop or Garmin pushes your HRV, sleep stages, resting heart rate, and recovery score automatically while you sleep.

02

AI recalculates your day

StrainCoach analyzes your readiness against your training block, race timeline, and accumulated fatigue to build today's optimal session.

03

Train with confidence

Open the app, see exactly what to do and why. Chat with your AI coach anytime to adjust for schedule changes or how you're feeling mid-session.
