Someone on my friends list must know these things...
When I exercise strenuously, I'm much less sore the next day if I stretch out both before and after the exercise. Is it best to stretch immediately before and immediately after, or to wait a few minutes in between?
I'm pretty sure it's better from an aerobic point of view to stretch immediately before and after, since that will extend the period when your cardiovascular system is getting a workout, but that's not what I care about; I care about reducing next-day soreness.
When I do a weight-training exercise (specifically push-ups, if it makes a difference), and do multiple sets, what's the right length of time to wait between sets? I've been doing as many as I can, then waiting long enough that I can do about 80% as many in the second and third sets.
