My workouts include aerobic exercise for a healthy cardiovascular system strength training to maintain muscle tone and bone density core strength exercise for a stable mid-section and stretching to maintain mobility.
Weight-bearing exercise builds bone density builds your muscular strength so that you can hold your body up where those bones have a tendency to get weak.
Certain kinds of speed flow intensity density of attacks density of interaction... Music that concentrates on those qualities is I think easier achieved by free improvisation between people sharing a common attitude a common language.
I think there's nothing better than seeing a three-chord straight up rock 'n' roll band in your face with sweaty music and three minute good songs.
