So yeah. I was thinking of this when my legs were burning during gym when I had to do 30 Burpees.
All it is is, post painful sounding posts. [/title] also cringing/ sick stomach count.
I'll start:
Imagine having yourself strapped to a pole, and having your feet touch burning coals no matter what.
Or pins and needles stuck on your feet and if you sit, you get a headache.
