A plank challenge always starts the same way: a screenshot, a 30-day grid, big intentions on day one. Then day four hits, nobody's checking, and the timer quietly stops mattering. Without stakes and without proof, a plank is just you, a floor, and a clock you're free to cut short.

  • You start strong, then skip a day and the whole streak silently falls apart.
  • Nobody is actually watching, so a shaky 40-second hold gets logged as a full minute.
  • Group challenges run on the honor system, so you never really know who held and who fudged it.
  • There's no reward for grinding it out — you suffer through the shakes and get nothing but a checkmark.

How Cadoo solves it

Real money makes you hold longer

When your own cash is riding on the hold, quitting at 45 seconds suddenly isn't an option. Cadoo turns your plank goal into a bet, so the burn in your core is backed by a reason to push through it.

Your camera times every second

Cadoo verifies your plank hold on camera and scores your form, so only a real, honest hold counts toward your time. No screenshots, no honor system — just a hold you actually earned and can stand behind.

Compete, climb, and share the win

Bet against friends, ride the leaderboards, and climb the leagues as your hold time grows. Then turn your best hold into a shareable, skinned highlight clip worth posting.

Frequently asked questions

What is a plank challenge?

A plank challenge is a test of how long you can hold a plank — often stretched over days or weeks as you build up your time. On Cadoo, it becomes a money game: you stake cash on your hold, prove it on camera, and compete against friends to win the pot.

Can you really make money on a plank challenge?

Yes. You put money into a Cadoo game, hold your plank to hit the goal, and win real payouts when you come out on top. The stakes are the whole point — money on the line is what keeps you holding when your core starts shaking.

How does Cadoo stop people from cheating?

Cadoo verifies your plank on camera and scores your form, timing only the seconds you actually hold with good position. Because every hold is verified the same way, nobody can inflate their time, and the winner genuinely earned it.
