I still use them. It depends somewhat on the needs of the athlete and the time frames of preparation. Eric and most of the other post-collegiates will be doing them after this short introductory cycle. I didn’t get them from LSU. During my time at LSU and first year at USMA, I experimented a lot using quite a few exercises in various sequences and loading patterns and via statistical analysis on the test data was able to come up with some general guidelines for progression of exercises as well as what tests correlate with what performances (in my training protocols).
