Built for the climb

MY LEGS HURT.

A fitness tracking system built for real outdoor training locations, starting with Perth's Jacob's Ladder.

Your legs already hurt. You may as well get credit for it.

Built where ordinary fitness tracking falls short.

Jacob's Ladder is simple on paper: down, back up, repeat. Accurately recognising those laps with a phone is anything but simple. My Legs Hurt was built and tested on the course itself.

The system

Track the workout.
Recognise the lap.
Earn the time.

The app is designed around the workout first, with verified timing available when the location and sensor evidence are strong enough.

Automatic Lap Recognition

Train without manually counting every lap. My Legs Hurt is designed to recognise completed laps automatically while you focus on the workout.

Workout History

Keep your sessions, lap results and progress together so you can see the work you've actually done over time.

GPS Verified Timing

Competitive timing is awarded when the available location and sensor evidence is strong enough to support it.

The lap is the achievement. The time is the bonus.

Built outside the lab

Tested on real stairs, with real phones.

My Legs Hurt is being developed from real Jacob's Ladder sessions across different devices and real-world GPS conditions.
