Hi,
It can vary. Bouncing, is to get the qi moving. You also breath out, through your mouth. This as a releasing and cleansing(you can, really empty the stagnant air out of your lungs too, completely exhaling), a letting go/shaking off, of where you come from. You are moving your focus and intention towards a session. Each day is different, regarding your physical state, and can be different in how you express bouncing. It should be flexible, and not practiced as one preset way being more beneficial than another. I probably, bounce differently on a Minnesota winter morning too, so it may also relate to the setting. I might need to generate some serious heaT! -gallen
