Brookfine, a little friendly advice for you: We're all interacting with a lot of people here, mostly sight unseen. To expect folks to remember or search up details about you elsewhere on the board that are relevant to this thread is unrealistic. For example, you yourself are saying that you think everyone here is over college age, and that it's been 5 years or more since anyone of that age was here. I can think of multiple examples of people posting fairly recently under 30, not to mention people asking questions about others who are.

Your interlocutors here are doing this for free, for fun, for the benefit of others, and to be part of a community of sorts. Repeating relevant information within the thread, or answering questions about such for an additional time is part of the deal. It's the "put the cookies on the bottom shelf" idea to make things simple for the people with whom you're communicating.

As to injury prevention, folks are not likely to Google injury prevention for your specific sport, when one of the basic principles on which the SS method is predicated is that strength is a general adaption. Sure, lots and lots of running coaches and programs insist on specific, targeted exercises, but that doesn't mean that it's right. If you're familiar with Rip, et al. on physcial therapy and such, you can deduce why the main line of advice will be to get generally and comprehensively stronger. Abductors, adductors, and even hip flexors are strengthened by the major lifts. Combined with sport practice, are you sure you need the accessory work, or is that just what everybody does?

If your grey book has a black cover, it sounds like it's an older edition. The books are updated over time as new information is learned, so it may behoove you to check out the current one. Rip has the integrity to change the material as needed over time.
