Integrates with Garmin Connect

AI coaching powered by your Garmin data

TrainState connects to your Garmin device to analyse training load, HRV, sleep, and recovery — then uses AI to deliver personalised coaching insights and tell you exactly what your body needs today.

How it works

From raw data to actionable coaching

01

Connect your Garmin

Authorise TrainState to access your Garmin Connect data using a secure OAuth connection. We sync your activity history, HRV, sleep, and training load — nothing else.

02

AI analyses your data

Our AI reviews your recent training load, recovery trends, and readiness indicators to understand your current physiological state — not just yesterday's workout, but your patterns over weeks.

03

Get coaching insights

Receive personalised recommendations: what to train today, how hard to push, what to watch for. Backed by your actual data, not generic advice.

Features

Everything your coach needs to know

Built for performance-focused athletes who train consistently and want data-driven guidance — not generic wellness tips.

Daily readiness score

A composite readiness assessment based on HRV, sleep quality, training load, and body battery — so you know before you train.

HRV & recovery tracking

Track heart rate variability trends over time. Understand your baseline and see what genuinely affects your recovery.

Training load management

Monitor acute and chronic training load (ATL/CTL) to stay in the optimal training zone — building fitness without accumulating dangerous fatigue.

AI coaching insights

Plain-language coaching that explains not just what to do, but why — based on the specific patterns in your data.

Workout recommendations

Session suggestions tailored to your readiness state — cardio workouts pushed directly to your Garmin watch, strength sessions with a built-in logging interface.

Sleep analysis

Sleep is the primary recovery lever. TrainState tracks your sleep duration and quality trends and factors them directly into daily readiness.

Data & privacy

What data we use, and why

TrainState accesses your Garmin Connect data only with your explicit authorisation. We use the minimum data required to provide coaching insights — nothing more.

Heart rate & HRV

Primary recovery and readiness indicators. HRV is the most reliable daily metric for assessing training adaptation.

Sleep data

Sleep duration and quality score from your Garmin device. Sleep is the single biggest lever for athletic recovery.

Training load (ATL/CTL)

Acute and chronic training stress from your activity history. Used to calculate fitness, fatigue, and form.

Body battery

Garmin's composite energy readiness metric. Used as a cross-check alongside HRV and sleep data.

Activity history

Recent workout type, duration, and intensity. Provides context for load calculations and coaching recommendations.

Resting heart rate

A secondary recovery indicator tracked over time to identify stress and fatigue trends.
