Using Soft to Overcome Hard

[LFJ]

For 50 students of my class, not a single student could use single "left" arm to block my 45 degree downward body rotation "right" haymaker. My haymaker could not only knock through their left blocking arm, it also hit on the side of their head which knocked their body to be off balance.

And those students were likely using forceful blocks too.

Stonecrusher is saying to use soft to overcome hard by just "leaving your hand out" "totally relaxed" and letting their attack run into it...
