Don't ask why . . .

because my answer will be stupid . . .

Burpee challenge:

Every day for 100 days, do one burpee the first day . . . 2 the second . . .

Today is day four, and I did 10 to catch up. At least tomorrow I only have to do 5 . . .

At the end it will be something like 5000+ burpees for all the days.

Of course, if you miss a day, you have to do the previous days as well. So don't miss the last three days . . . .

You can do them in any way order form you want, so long as you do the required number by midnight . . . .
