Why are the other apes so much more stronger than us?

The fact that the Gorilla is so much stronger than man seems obvious by appearance, though I am sure there may be more to it, but even the average Chimp or Orangutan seem to exhibit raw strength that competes with even the most elite strength athletes. Why are they so strong? 

Also, why did we not retain this strength? The most obvious argument that I can think of is that we traded fast twitch for slow twitch muscle to allow more endurance, but Chimps and Orangutans seem to have quite a bit of muscle endurance also.

Several possible reasons:

1) Other apes live more active lives than we do.  A particularly fit human who lifts a lot is obviously going to be much closer to other apes.

2) We left the trees.

3) We have much better fine motor control than other apes.  It's hypothesized that this is due to a change in muscle architecture that decreased our raw muscle strength.  So a tradeoff for better tool use, basically.
