5 signals your body sends before you feel them

The short version

  • Resting heart rate drift
  • Left vs right imbalance
  • Recomposition the scale hides
  • Sleep debt stacking
  • Load outrunning recovery

Resting heart rate drift

A few beats above your baseline across a week. Connect WHOOP or Oura and it's on the chart before the tiredness is.

Left vs right imbalance

A scan measures each side. Small gaps become the tweak that sidelines you — and you'd never spot it in a mirror.

Recomposition the scale hides

Fat down and muscle up can land on the same weight. The scale calls it 'nothing'; the scan calls it a win.

Sleep debt stacking

One rough night is noise. Four in a row is a pattern — and it shows in tomorrow's readiness before you feel foggy.

Load outrunning recovery

The ratio tips quietly, not with a bang. Catching it early is the difference between a deload and a setback.

Measure it instead of guessing

Arveno turns one photo into honest body-composition estimates — labelled as estimates, tracked as a trend. The first scan is free; membership is £1.99/month or £19.99/year, with the first 7 days free either way.
