Most people that are joining this challenge already know who I am, but if you don't, I'm sure you'll find out soon enough .. lol. I am in no way a fitness expert, but I like to set up challenges for my friends. So far we did a plank challenge which I totally rocked and just last month was a pushup challenge which is still ongoing (as for me, I totally failed that one!) So, see, I'm not perfect in these, but crunches is something most of us can do throughout the day - no limit - just do as many as you can and add five the next day - simple! Let's do this.
