The agility ladders are used mostly as a warm up, but they also teach body control and athleticism. The entire warm up procedure is fantastic and it takes from many different sources such as Mark Verstegen of Athlete’s Performance.
I think some of the pitching specific workouts are great. The lateral plyos and angled plyo box step ups are perfect for pitching and also teach how to pelvic load or simply lead with the hips (probably the most common advice on this board). All of the medicine ball work puts a pitcher through similar movements that he’ll find on the mound. I think the best part about them in this program is that everything is measured, from velocity of a med ball throw to number of med ball taps against the wall. This helps to show improvement and to make sure that the workout is being performed at a high level.
The arm care section is basically a full rehab program using tubing, 2 lb sand ball, mini trampoline, bodyblade and other techniques. I think every pitcher should perform some sort of rehab program every offseason to prevent injury.
The backward chaining section helps to develop arm action and full body movements while starting at release and building up toward throwing off a mound. It uses some weighted and underload balls, but it’s definitely a nice progression to use before pitching. Long toss is encouraged in a similar way that Alan Jaeger teaches.
All together seems like a very good pitcher specific program that can be used with some weight lifting to provide great results.
