Aikido Warm-up and Ki exercises

It never ceases to amaze me what you can find on YouTube. I just discovered this excellent short video in which Tohei Sensei (founder of the school of Ki Aikido) demonstrates a number of the warm-up and 'Ki development' exercises which often precede classes of Aikido. If you are learning Aikido, this video provides a good reference. I am in the process of providing some annotations to help you recognise the various exercises being demonstrated.

The names of each exercise and a short description are given below. The numbers refer to the times in the video:
