The plyometrics and the heavy leg work were done on the same day, twice a week.
Sprinting was a day all it self. Inclined sprinting was used a lot. This was either once or twice a week depending on the workout.
By the end of my training, I could run a 6.6 second 60yd dash. For reference, Deion Sanders ran a 6.2. My 40yd was about 4.5. My off-the-line speed wasn't as good, but my top end was really good. I could go at 22mph on the treadmill. They had a "20mph club" and I got 22

The fastest I saw on there was 25mph and he was an olympic sprinter. They trained olympic athletes there as well.
I'm not sure what my vertical was, but I know it was impressive. I could jump to eye-level with the rim. At 6'2", that's skying.
Of course, I weighed 175 lbs back then. At around 240 now, I can still dunk, and I attribute that to the power of my legs from heavy leg work. I can't jump so the rim is eye-level, but I can get up and put it in.
So, I know that that shit works like a dream.
What was cool is I usually did my training sessions alongside Jeff Hornacek's son. Jeff was there a lot of the time and I got to talk to him quite a few times.
There was a basketball tournament at my high school on a saturday that same year, and my friends said John Stockton and Jeff Horncek were there. We were already there for a baseball practice and I was all "Oh, I Know Jeff, he's cool" My friends didn't believe me. I went up to him with my friends, sitting next to John Stockton and I said, "Hey Jeff what's up". He was like, "Oh, hey Mark, what's up man?" My friends couldn't believe it. Hahaha, it was funny.
