According to Wikipedia, “the hands must touch the sides of the body…Rigidity of the body must be maintained to constitute good planking”. Jingheng, remember to plank better next time!
Googled to find out what planking has been done. A lot! Here is one that I like – a wedding plank from The Official Home of Planking
And this – a cabin plank. You have got to give it them for getting him up!
Well well! We have our very own planking community in sunny Singapore – 3K fans strong on Planking Singapore FB. I can see recent posts, so yay, we are not so outdated here in Tianjin!
