First thing, there are a LOT of categories in there, however it's not as much as it seems at first glance. For starters, a single exercise can, and usually does, check multiple boxes. Second, there is a column dedicated to the question - "Is this necessary?" with a simple yes/no answer (if it falls under something other than those two options, it's almost always a "no"). For example, soccer athletes have less need for upper body strength than athletes from other sports, such as football, so it's not as important to check all the boxes for upper body press/pull sections. Let's go through the list and break down the individual sections. As mentioned in part 1, "horizontal" and "vertical" refer to the standard anatomical position.
Both upper body sections contain the same qualifiers, and for good reason - we want to balance pressing and pulling. Balanced does not always mean equal, and I have leaned towards a 2:1 or even 3:1 pull to press ratio, with more horizontal pulling/rowing than vertical. The reasoning for this is simple - first, most of our time is spent hunched forward (looking at our phones, sitting at a desk, watching TV/playing video games, etc.), so from a preventative standpoint, we want to work on resetting and improving posture. Second, most athletes want to bench, so they are likely to do additional benching on their own and we need to balance that out. Last, I've never had an athlete with problems because their back was too strong. A strong back is immensely helpful in maintaining shoulder and spine health.
Next, each upper body and lower body section includes unilateral, bilateral, eccentric, and isometric sections. Limbs need to be able to work independently as well as in concert with each other, and we need to be able to control and apply force at all phases of movement. Overlooking eccentric and isometric contractions can impact performance and increase injury risk. Athletes need to be able to do more than accelerate a load/movement, they must also be able to decelerate and transition from deceleration to acceleration. These two categories help ensure we train all three phases of movement.
Lower body movements are split into two main categories (as covered in part 1) - knee hinge/squat and hip hinge/deadlift. The determining factor between these two categories is the amount of knee flexion - knee hinge exercises involve maximal knee flexion, while hip hinge movements have minimal knee flexion. In addition to these two, I include a category for "power movements", this can range anywhere from jumps to Olympic lifts. Basically, let's make sure we're not just moving big weights, but also making the athletes twitchy and explosive. In team sports, strength means little if we can't generate it quickly.
Next, we have center axis, or functional core, exercises. We want to train the core in all three planes, and in three different ways - generating force (least common/important), resisting force (anti-extension/rotation, very important), and transferring force from lower limbs to the upper limbs or vice-versa (total body movements, most important). Similar to athletes doing bench press on their own, if you're going to minimize focus on one of these areas, let it be generating force, as athletes tend to do plenty of crunches and similar ab work on their own.
Finally, there are a handful of categories that deserved their own section. Hip/shoulder activation should be occurring in the warm-up or prep work with minimal load, such as band work. These are just to prime the muscles for the main lifts of the day or serve as correctives to address imbalances. With bodyweight (chin ups, push ups, etc.) and locomotion (sleds, sprints, etc.) movements, it's important to remember that very few sports focus on athletes remaining stationary, so we need to make sure they can move their bodies in addition to outside resistance. Finally, loaded carries are one of the most overlooked X-factors in training. They are a great way to develop hip, core, and shoulder stability, as well grip strength and moving under a load. Looking back, I'm disappointed in how long it took for me to adequately utilize them in my programming.
Not every exercise has a clean fit into a specific category (such as incline bench), but overall this provides a decent framework to build upon. This is another tool for the toolbox and can help answer the "why are we doing this" questions. Remember, if you can't answer the "why", then the exercise doesn't belong in the program.
