Why I built it

Like almost everyone alive, I've struggled with keeping up with the gym. My most committed period was when I worked with semi-personal trainers — I say semi because most sessions were one trainer for roughly four people, so it wasn't exactly personal training.

Training at La Salle Du Temps taught me that working out is really about doing the simple things over and over again. Reading Mark Rippetoe's Starting Strength: Basic Barbell Training solidified the concept for me: focus on a few simple compound movements with a barbell, and gain strength.

So I started training this way, but my process for recording workouts was terrible. Sometimes I'd write the correct weights; other times I'd use abbreviations I'd forget the moment I stepped out of the gym, leaving me confused at my next session.

With this app, all I wanted was something that would help me track and measure without distractions — and guide my sessions, so I know what to do and when.

Lessons learnt

• Simpler apps are more interesting for me and my coding agent: the idea is clearer, and getting to a solution happens faster
• Giving a coding agent user stories, and making sure there's a clear image or prototype of what's being built, is important for keeping the agent on track
• Make the agent audit page after page, check the details, and ask it to correct things
