Although running form may be decent for the first part of a long run, as my muscles get tired, they weaken and my legs begin to get angled inward, putting a lot of weight on my knees. Practicing good form is of course a virtal part of running, but I began to wonder if perhaps weakness in my thighs and hips were making that more difficult than it needs to be.
A couple of years ago I came across the weight lifting program I've enjoyed the most so far: Greyskull LP. It allowed me to see quick results, and focus on compound lifts. That said, I've also tried other popular exercise regiments like AllPro, but Greyskull were the one I liked the most. Everytime I've gotten started with Greyskull LP again, I've re-used my aging Excel / GDocs spreadsheet (often printed out).
When I started looking for an app to replace the spreadsheet, I found only one made specifically for GSLP, and I found it to be more lacking in both design and functionality than my spreadsheet was. I realized I could probably make an app that just re-implements my spreadsheet but with a nicer design, and add whatever features I felt couldn't be accomplished by the spreadsheet — so I set out to create an app just like that.
Having originally hoped it would take less than a weekend of work, I ended up in a rabbit hole of both restructuring code (from originally using Apollo with link-state-local, to using a redux style architecture with the new React.Context API).
Now the app is more or less finished and although it was originally intended only for me, I thought perhaps other people would like the same app, and decided to publish it on the app store: This is the first app I've actually finished and published!
