Create a private circle and choose one shared activity: a short walk, recording a 2 km starting time or an optional shared weigh-in. Let people choose whether to participate or share.
Compare your current result with your own starting point. Use cheers for effort and care. Weight records from the personal log never enter a circle automatically, and shared results can be removed.

Agree on one kind rule before starting a challenge.
Small steps make a difference too.
