Weight is part of wellness check-ins but has its own chart and goal tracking.
Activate
Settings → Tracking → Wellness check-ins → enable Weight. Use the arrows to position it on the check-in card.
Log weight
Day view → wellness check-in card → enter today's weight. Units are kilograms. Tap the field on any day to correct that day's value.
Your profile weight
Your athlete weight (used for W/kg and coaching) lives in Settings → Sports Settings → Weight (kg). By default it syncs from Intervals.icu; type a value to override it manually, and use the 'Use synced' control to switch back. Log your body weight without the bike — bike weight isn't part of your athlete profile.
Set a goal
Analytics → Weight chart → tap the goal pill to set or change a target. It shows as a dashed 'Goal' line on the chart.
Sync
Weight syncs bi-directionally with Intervals.icu. A smart scale that feeds Intervals.icu (directly or via Garmin, Whoop, etc.) lands in LeCoach automatically, and weights you log in LeCoach write back.
