Why is it so hard for you to understand that the guy was vaulted with no
warning so he took the full hit, why is it so hard to understand that he
would put his hands and feet down before he landed? Did you watch the
video, the guy was reaching for his lower back before he even hit the
floor.. On paper, maybe you are right, must be an engineer thing
Technitions usually are the ones to put stuff into practice anyway

The *total* force needed to lift the man off the couch to apex and then
from apex to stationary on the couch again will be equal. The difference
is in the total amount of time that force is applied.
It's no different from a man climbing a 100' ladder or being shot out of a
cannon to a height of 100'. Both take about the same amount of energy (
exactly the same in a vacuum), but I'd bet you'd rather climb.
They'd have to shoot me out of a canon, since I'm afraid of heights.
