Assuming the distinction between the two isn't a myth, I have lots of fast-twitch muscles and very few slow twitch, so lots of immediate strength, but no stamina. At all. Exercises in crappy periods often turn out more to be about keeping me limber than building up strength - that and keeping my core muscles strong so I don't end up going all Picasso. Lifting Heavy Things reminds me that I can get stronger *as well* which is just an awesome thought - I can't run away from trouble, but perhaps I can throw a bus at it.
