How it's counted
- Log crunches, curl-ups, or dead bugs toward 1,000 total — about 33 a day
- Feet not anchored on crunches/curl-ups; break into small sets
- Note your variation in captions
- Form over speed: no yanking on the neck
- Share a core finisher photo
- Back pain or a disc problem, or pregnant past about 20 weeks or had a baby recently: do dead bugs instead, they count.
- Muscle burn is normal. Chest pain, dizziness, unusual breathlessness or sharp joint pain: stop and get checked.
FAQ
Is it free?
Yes. Every Adi.fit challenge is free to join with a free account — no credit card, no in-app purchase.
Do I need any equipment?
None. Bodyweight only.
How much do I need to do each day?
Summer core. Travel, vacations, long days: keep a habit that fits anywhere. About 33 a day — crunches or curl-ups (feet not anchored) are the default; dead bugs count too.
Does it work with Apple Health or Health Connect?
Not directly for this challenge. By hand — log your number on the challenge page whenever you get to it.
What if I miss a day?
Nothing resets. It's a running total for the month, so a missed day just means catching up when you can.
Can beginners do it?
Most people. Dead bugs are the easier, safer option if you have back pain, a disc problem, or are pregnant past about 20 weeks or recently had a baby.
What happens when I finish?
You get a finisher card to share, and 1,000 Sit-Up Challenge comes back again next July — same rules, fresh start.
