Most people track too many things and end up tracking nothing.

After years of testing every fitness tracker and app on the market, I've narrowed it down to 3 numbers that actually predict whether you'll hit your goals:

1. Weekly training volume — Not how many days you showed up. Total sets × reps × weight. If this number goes up over 4-week blocks, you're growing. Period.

2. Protein per pound of bodyweight — Forget macros apps with 47 fields. Track one thing: are you hitting 0.8-1g of protein per pound? Yes or no. Everything else is noise until this is locked.

3. Sleep consistency score — Not total hours. The standard deviation of your bedtime over 7 days. If you're going to bed at 10pm Monday and 2am Friday, your recovery is tanked no matter what your Oura ring says.

That's it. Three numbers. Track them weekly. Ignore everything else for 90 days and watch what happens.

This is exactly what we built TrackWell around — cutting through the noise so you actually make progress.
