The old way

Your last online fitness challenge ran on spreadsheets.

A Google Sheet of names, bank transfers to match by hand, a PDF program emailed to everyone and a WhatsApp group buzzing at midnight. Then weigh-ins to chase every Monday, before and after photos to sort, and a winner to pick from a pile of DMs.

  • Payments to chaseMatching bank transfers to names and chasing the people who said they'd pay later.
  • Weigh-ins by handCollecting weights every week and working out who should move to a different plan.
  • A finale that eats your weekendSorting photos and answers, then counting votes in a group chat.
The Kahunas way

Set it up once. Kahunas handles every week after that.

Entry fees paid upfrontCharge a one-time entry fee through Stripe or PayPal. A place is only confirmed once the payment is.
Released week by weekTraining and resources open week by week at your release time, in the challenge's time zone.
Weigh-ins suggest the planMembers log their weight each week and are offered the nutrition plan whose calorie range fits them now.
A finale with a winnerMembers send a finish form, you shortlist finalists, and everyone votes for the winner.

Switch on what they get. Their app shows nothing else.

Group chat, one-to-one messaging, check-ins, supplements and daily habits can be switched on too.

  • Training waits for their starting form
  • Late joiners start in the current week
