This is a sample "Fitness Routine" that we used at Goshen High School when I was an assistant in the boys basketball program for Mike Sorrell. It was adapted for high school from a similar program that Coach Paul Patterson used at Taylor University. Our pre-season program consisted of lifting on Mondays Wednesdays and Fridays and doing this agility routine on Tuesdays and Thursdays. I am offering this as a template to adapt to the agility exercises you currently do.
To set up the program, you must go through each exercise and what the proper form is for each one. It does not do anyone any good to go through the exercises just for speed without regard for correct technique.
On the first day that you do the program, each player starts out on Level I. Start the routine and a stopwatch. Each player works at his or her own pace to complete the number of exercises in each category for Level I. The time for the routine is 20 minutes. Coaches work to correct technique. Each player has a laminated copy of the above chart to use as they go through the routine so that they are aware of how many reps are required for each exercise for each level. Any player who completes level I says time and a coach records their time. If a player does complete within 20 minutes, they move up to the next level on the next fitness routine day.
What I like about it is that it is flexible and that you can have freshmen working at the same time as returning varsity players, but neither group is influencing the others. No one holds anyone back and at the same time, younger players do not have to perform up to standards for the veterans.
