TRAIN
- Coach-built programs and the workout of the day, with plates & warm-up, exercise swaps and demo videos
- An exercise library of over 400 movements, each with a video, level, what you need, how to do it, cues and common mistakes — filter by the equipment you own
- Show up and it shows: every class a coach confirms counts toward your month, your place on the month board and your history
- Log sets where you lift, with a rest timer that runs on your lock screen and in the Dynamic Island
- Offline logging: everything syncs when you're back on signal
- PRs, streaks, training load and readiness in Progress

EAT

RECOVER

TEST
- Your Onyx Score, domain profile and testing results with what-changed verdicts and retest reminders

COACHES
- Coaches use the same app: confirm attendance after class, add walk-ins, change the day's WOD, post announcements, message athletes, enter field-test results, and work through one Reviews inbox of workouts, flags, check-ins, videos and test sessions

PARENTS
- Sign in with a parent account to follow your athlete's training, testing and bookings, book classes and sign documents on their behalf
