You are communicating the resistance of the ground to the force of the blow - and you deform (strain energy) according to the limits of your structure. You are primarily limited by the strength of your structure in that interaction.
Yes, but we're talking about a baseline exercise
to develop a baseline skill
.... (i.e. strength of your structure).... a constant push is hardly acceleration.
The exercises that have been mentioned thus far, Mike's lunges, Ark's body axis, shiko, etc. are all related to this - developing structural strength and integrity, as part of the baseline skillset - i.e. body conditioning - using the same basic principles common to all Asian MAs.
