• Digital Twin — a new home for your measured body. Your heart, recovery, sleep, and aerobic fitness on one page, every number labeled measured or estimated, next to your 3D avatar and tape measurements. Then take it for a run on the simulation bench: ruck-march standards, race predictions with plain-language training plans, multi-day trip planning with food-and-water math, stair climbs, and a what-if slider that shows how losing or gaining weight would change every result. Free accounts get a fully interactive sample body — Premium runs it on yours. • Fitness tests — log push-ups, plank, 2-mile run, deadlift, grip strength, jumps, shuttles, loaded carries and more, with how-to instructions on every test and context from published standards. A timed 2-mile or Cooper run measures your aerobic ceiling — no lab needed. • Google Health connection — link your Google/Fitbit account for richer sync: per-workout heart-rate curves, max heart rate, and 1-minute heart-rate recovery. • Garmin support — import activity files or a full Garmin export, including sleep. • Coach upgrades — a redesigned messaging hub and richer client views, always under your sharing controls. • Cycle tracking — tap any calendar day to log flow; predictions and fertility windows use it. • Honest calorie targets — targets adapt only when your logging truly supports it, and a new "how you eat" setting (like two meals a day) keeps daily expectations fair. • Plus: clearer lab-upload guidance (including a simple spreadsheet format), easier time entry, and a fix for a stuck zoomed-in screen.
