Eli5: How are the different types of "athletic" muscle different?

I've seen so many different builds on the "muscular" spectrum, ranging from barrel-shaped power lifters, to wiry, waifish dancers and acrobats, to really chiseled and defined bodybuilders. I know they're all strong and ripped in their own way, but what's the difference as far as approach and training?

You pretty much answer your own question. Power lifters need to have high force output which is accomplished by large muscles, dancers need long, lean, fast twitch muscle for quick movements and lots of flexibility. Your primary training is always by doing the activity you are training for, weight lifters lift larger weights, runners run, climbers climb. Each group targets strength training in a similar philosophy as the sports they are training for.
