Exercise While Waiting for the Lift

This is a fun kind of “advertisement” spotted on an elevator in Bangkok by @calum1975. It is in Thai and English and gives you some tips of exercises that you could do while waiting for the lift to arrive. As it is numbered 11-13, I presume that there is a different set on each floor. The exercises include standing on toes and heels, stretching and my favourite, “using the stairs”!
