Wearables

You can't out-train bad sleep — and your composition proves it.

The short version

Sleep is when you adapt

The session breaks you down; sleep is when muscle repairs and hormones reset. Skip it and you're training without the recovery half of the equation.

Short sleep tilts the math

Run low for a stretch and appetite, cravings and stress hormones climb while training quality drops. The composition maths quietly tilts the wrong way.

The scale hides it, composition doesn't

Weight can sit still while lean mass slips and fat creeps up. A composition trend catches that drift a single number never will.

Your wearable already knows

If your recovery score keeps coming back low, that's the signal. Pair it with your composition trend and the story stops being a mystery.

Recovery low 3+ nights ✓ Cravings up ✓ Lifts feel heavier ✓ Composition trend flat or slipping ✓ — that's sleep, not effort. Fix the nights first.
