  • Invite 3 friends via a simple link
  • Customize your group name and goals
  • Start a shared streak you build together

Track Workouts with Your Core

Tracking workouts in a 4-person group is about keeping the group streak going. A scheduled day counts when everyone shows up, and a missed day can break the streak. That's what makes every workout count a little more.

Easy Logging

Track live, sync your health app, or log by hand.

Shared Streak

Stay Consistent with Group Social Motivation

Everything's more fun with friends. In a 4-person group, you always have someone in your corner. See what your friends are up to, send Sparks, and cheer each other on.

  • See when your Core logs a session
  • Send "Sparks" to cheer, celebrate, or nudge a friend
  • Celebrate milestones and keep the group streak going
