Have biologists identified "training" behavior in primates? Wouldn't chimps who develop a workout(bodybuilding) culture have great advantages?

A human bodybuilder can burn thousands of extra calories per day, and maintaining extra muscle mass requires the expenditure of lots of time. 

Neither of these things are feasible for chimps, who move constantly to forage for food. 

And it should be noted that chimps are much stronger than humans, proportionally. So increased strength would mostly be useful in internal confrontations. BUT: confrontation within a group is more efficiently handled through negotiation, display, and appeasement, not physical conflict. And confrontation between groups, for the vast majority of chimp evolutionary history, was most efficiently handled by group display which ended in one group moving on.
