Data Stories

Four numbers. Ignore the rest.

Your apps show you about thirty. Most of them are weather, not climate.

Lean mass trend

Not today's figure — the direction across weeks. Lean mass holding while fat mass falls is the whole game, and it is invisible on a scale.

Working-set strength

What you lift for real reps on a normal day. It is free to record, hard to fake, and it tracks whether the muscle you are keeping actually works.

Sleep duration, weekly average

The average, not last night. One bad night is noise. Seven of them is the reason your training stalled and nothing else you change will outrun it.

Protein, most days

Not every day, most days. The number you can repeat when the week goes sideways is worth more than the number you hit twice and abandoned.

Screenshot: the four, and the noise

TRACK — lean mass trend, working-set strength, weekly sleep average, protein most days. IGNORE — daily weight swings, single-night sleep scores, calorie-burn estimates, step-count guilt. Four inputs you control. The rest is a number watching you back.
