I'm also going to start training you not to freeze or hesitate in unexpected confrontations." Before we began, I thought I had pretty good physical strength and stamina, but I learned both could be better. We started out with a brief introduction to the equipment and layout of the space, and then moved on to an explanation of both fighting and neutral/passive stances. We warmed up with basic bodyweight calisthenics; then progressed to "tagging," where we tried to tag each other's shoulders and knees while standing face-to-face and blocking countermoves. Parker was amazing at tagging, of course, but I started to get the hang of it. The majority of the time, however, was spent covering groundwork and I really sunk my teeth into that. I knew very well what it was like to be down and at a disadvantage. If Parker noted my underlying vehemence, he didn't comment on it.
stretch. Another trainee, a 43-year-old marathoner with an 8:30 mile pace, couldn't even complete three 400-meter sprints at the beginning of training. She had "no gears," as Brian put it: she couldn't maintain a 7:30 mile pace for even three minutes. Two months prior to the New York City marathon, Brian had her do 16 minutes of total sprint training per week, in addition to four conditioning workouts per week using weights and calisthenics. Total workout volume was less than three hours per week. She called him daily the week prior to the marathon, often crying, pointing out the obvious: "This will never work." It worked. She finished the marathon in 3 hours and 32 minutes--an 8-minute pace, 30 seconds per mile less than her previous time--and she would have nished much sooner had she not stopped to help another runner at the end. Had she not stopped, Brian estimated her truer finish time at 3:30, a 7:28
