Ha, ha! Dan, you are a maniac! I already warned the incoming Freshmen I'm sending to Lane that you may look old, but you will kick their butts in the weightroom and on the drills!!
Hope you have a great meet today, I wish I could go
My "training" doesn't come close to these guys, but may provide some alternate ideas. I have found that avoiding the jogging altogether has helped my knees and back:
I vault two days/week; 1 long, 1 short. Both days include a dynamic warmup with pole runs, drills, strides, etc. I usually finish with some plyos and bleachers.
Gymnastic drills 2-3 days/week. Rope, rings, highbar, lowbar. Usually 3 sets of as many as I can do with each exercise.
I work nights and have my kids every day, so I try to fill other times with activities that help general fitness, but don't beat up the joints too much:
Frisbee golf with kids 2-3 days/week. Playing with kids 7 days/week. Rock climbing with kids 2 days/week. Swimming with kids 2-3 days/week.
Good luck!!
