I agree, I wouldn't consider either. I look at it like this, if we were in the middle of nowhere and my "deadlift" max is 600 and something 600lbs fell on you, you better hope that 600lbs is without straps.![]()
lol, point taken.
You have a point about the difficult aspects of sprinting donwnhill. But I personally think you're stretching the analogy a bit.

And running or sprinting dowhill would probably be a pretty good way to break a lot of bones and kill yourself, so I hope nobody tries it.
