Bouncing is not the same as the heal troubles. It is usually done flat footed. The foot remaining in contact with ground all the time. Although I think some people take the bouncing literally, and there is nothing wrong with that.
So just start in the stance for active exercises. Feet on the ground and flex at the knees to get the up and down bouncings. When you get ready to start the meditation (sitting or active), just gradually reduce the amplitude of the bouncing and come to a resting stance.
Breath in through the nose and out through the mouth. It is a relaxed rather than athletic practices. Eyes open or close, as you want.
I'll leave the Gallen part for gallen himself.
You are perfection.
