I just heard in the news something I find inspirational, and I think others who include a regular regimen of exercise will enjoy, Music and Exercise. I have suspected as much; the theory being that when listening to music during extended cardio activity, the brain sort of "sharpens" itself.
I listen to an MP3 player on my 4 mile runs, and since I alternate daily with long distance swimming (the MP3 player doesn't work so good there...), I try to think chords, theory, fretboard patterns, between turns. I always seem to come up with my best ideas when I come out of exercise, and this combination works for me.
How about you other "athletes?" (No Dale, 12 ounce curls don't count as cardio...) Anybody for a little "air mandolin?"
