Data Stories

5 numbers that matter more than your weight

The short version

  • Body fat % trend
  • HRV vs your own baseline
  • Resting heart rate drift
  • Muscle balance L/R
  • Training load vs recovery

Body fat % trend

Not today's estimate — the 4-week direction. That's recomposition, visible in data.

HRV vs your own baseline

Not the absolute number. 20% below YOUR normal means back off — whatever the leaderboard says.

Resting heart rate drift

Creeping up across a week is one of the earliest overreaching signals you'll ever get.

Muscle balance L/R

Small asymmetries become injuries. Almost nobody measures this. A scan can.

Training load vs recovery

The ratio, not either number alone, decides whether today should be hard or easy.
