If you dont try you wont know

Today I was doing v-up from Level 3 of Alex Silver Fagan's  Strong for woman, I kept my hand to the side to get up in the first round. In the third round by mistake, I tried and realised that I could do it. You fail by not trying.
It was funny while trying do a wind-mill wiht kettlebell on the high hand. I reduced the weight, then it looked clean and better.
