To complete this challenge, you need to do 300 crunches a day for 14 days in a row. You can do any variations of the crunch, in fact we recommend that you do different ones to target the different parts of your core. How you break up the 300 is up to you.
300 crunches a day for 14 days Challenge rules
- Not all types of physical activity are suitable for everyone. Users take Challenges and training advice at their own personal risk.
“300 in one set plus another 200 and I will do one more set of 200 later to hit 10,000 for the month. Hard to believe a couple months ago 100 of these burned something fierce.”
