A triangle is formed on the floor using the head and both hands. The larger the area of the triangle (i.e. the further apart the vertices are), the greater the stability. The body is stretched vertically upwards (bend the legs first, then bring them upwards).
The participants practise the movement form independently using series of pictures or based on the exercise being demonstrated by the instructor. The instructor (or a partner) gives feedback, provides support and checks that the exercise is being performed correctly.
