Weight, body fat, BMI, and VO2 max tracking

Praxis One logs body weight, body fat percentage, BMI, lean mass, and VO2 max as trends alongside training, nutrition, and recovery.

Body composition changes slowly, and the scale lies day to day. Praxis One logs weight, body fat percentage, BMI, lean body mass, and VO2 max as entries over time, so you judge the trend rather than this morning’s number.

Those trends sit next to calories, macros, strain, and sleep, which is where the explanations live. Lean mass going up with strength PRs is a good block. Weight going down with recovery scores falling and sleep getting shorter is a warning, not a win.

VO2 max, whether from your watch’s estimate or a lab test, is a useful long-term fitness marker for runners and cyclists. Log it in Praxis One and it stays with the rest of your data instead of in a separate app.
