Aim through the log at the block beneath it
Where to aim
At the block beneath, through the log. The swing stays accelerating rather than slowing as it arrives, which is the whole difference.
Where to strike
Near the edge rather than the centre for anything gnarly, and always through an existing crack if there is one.
Safety
Feet apart and outside the arc, and a low block so a miss goes into the ground rather than a shin. Standing logs on the ground is how people are injured.
