Track Workouts with Your Core

Tracking workouts in a 4-person format is about maintaining the group chain. Every time someone logs a workout, the group streak pushes forward. Miss a day, and the whole group feels the reset.

Stay Consistent with Group Social Motivation

We're wired to not let others down. With a 4-person structure, you harness positive social pressure. See real-time activity, send sparks, and keep each other out of the red zone.

  • Real-time alerts when your Core logs a session
  • Send "Sparks" to nudge those lagging behind
  • Celebrate milestone milestones and avoid breaking the chain
