Split the pot

10% is easier when you break it up, so each round has its own goal - and its own pot to split.

How do you verify the weight loss?

For all official weigh-ins, you'll be prompted to submit your official starting weight. Our standard weigh-in process involves you submitting 2 photos: one of you standing on a scale in lightweight clothing (no shoes, hats, belts, watches, coats, or outerwear), and another of the scale’s readout with your weigh-in word written on a piece of paper.

What you'll need

  • A scale (preferably digital)
  • A digital camera or smartphone
  • A full-length mirror or someone to take your photo

Why can I never get the scale picture to face upright no matter which way I turn the phone? I am still exceptionally bad at smart phone-ing. 😅

Well, Japan seems ready to take the step of “social distancing” just in time for this challenge to start.. so, hopefully I can figure out how to make this work without the availability of the gym! Good luck, everyone! 頑張ろうー

We already started in Nigeria and I then discovered the amazing world of YouTube workouts. You could try some of them. I’m currently doing popsugar. There’s also chloe ting, Sydney Cummings
