Start by hanging in a cat-leap/arm-jump position on the side of a wall with your fingers on top of the wall, on a ridge or a railing next to a wall, where you have a lower target wall/ridge/ledge/rail/bar that you lower yourself down to.
Demonstrate moving onto the lower ridge/ledge/bar by using both arms at the same time. Feet must stay on the side of the wall and cannot be used on anything else. This is called the dyno or double-tap.
The distance of the lower bar/ridge/ledge from the top one must be one step length (heel-to-tow) or more. Use your shoe to measure the distance.
Repeat three times.
You can change orientation and move to your left or right, as long as you are moving downwards.
The lower target does not have to be parallel with the lower starting position. You can use perpendicular rails, as long as the height requirement is met.
