Previously kcal was computed on-the-fly in 3 places with inconsistent
inputs (hardcoded 80kg, missing GPS data, no demographics). Now a
shared computeSessionKcal() helper runs server-side using the best
available method (GPS + real demographics) and stores the result in
a new kcalEstimate field on WorkoutSession.
Kcal is recomputed on save, recalculate, GPX upload, and GPX delete.
The stats overview uses stored values with a legacy fallback for
sessions saved before this change.
Fetch up to 6 extra measurements beyond the display limit so the SMA
window is fully populated from the first displayed point. For users
with fewer total measurements, use a reduced window with Bessel's
correction and sqrt(w/k) sigma scaling to reflect increased uncertainty.
Weight chart now spaces data points proportionally to actual dates
instead of evenly. Days without a weight log no longer compress adjacent
points together. Uses Chart.js time scale with chartjs-adapter-date-fns.
Add weekly goal as a solid horizontal line on the bar chart via a
custom Chart.js plugin. Cap bar width at 40px. Always show all 10
weeks including empty ones instead of trimming leading zeros.
Add cardioKcalEstimate.ts implementing tiered calorie estimation for
cardio exercises: Minetti gradient-dependent polynomials for GPS
run/walk/hike, cycling physics model, MET-based fallbacks from
Ainsworth Compendium, and flat-rate estimates. Wire cardio kcal into
SessionCard, workout completion screen, history detail, and stats
overview API alongside existing strength kcal (Lytle). Move citation
info from stats overview to clickable DOI links on workout detail
kcal pill.
Estimate strength workout energy expenditure using the Lytle et al. multiple
linear regression model. Maps all 77 exercises to 7 studied categories with
confidence levels. Shows kcal on stats page (cumulative), session cards,
workout detail, and workout completion screen. Supports sex/height demographics
via profile section on measure page. Includes info tooltip with DOI reference.
- Add metrics system (weight/reps/rpe/distance/duration) per exercise type
so cardio exercises show distance+duration instead of weight+reps
- Add 8 new cardio exercises: swimming, hiking, rowing outdoor, cycling
outdoor, elliptical, stair climber, jump rope, walking
- Add bilateral flag to dumbbell exercises for accurate tonnage calculation
- Make SetTable, SessionCard, history detail, template editor, and exercise
stats API all render/compute dynamically based on exercise metrics
- Rename Profile to Stats with lifetime cards: workouts, tonnage, cardio km
- Move route /fitness/profile -> /fitness/stats, API /stats/profile -> /stats/overview
