1. I’m speaking at the Massachusetts High School Baseball Coaches Association’s Annual Clinic this morning, so this week’s random thoughts will be somewhat abbreviated. I didn’t even have time to pick out this week’s music selection, so you have to settle for this dude getting owned!
2. Speaking of baseball, one thing I’ll be discussing in some detail is hip flexion range-of-motion asymmetries in pitchers. You’ll almost always see far more hamstrings flexibility on the front leg for obvious reasons, but it’s also important to consider how throwing styles contribute to this issue. Guys who throw on stiff front legs are ones who will most commonly present with big asymmetries. Justin Verlander would be a great example:
Guys like Verlander need to pay close attention to maintaining adequate length of the right hamstrings (the opposite would be true of a left-handed pitcher). Conversely, a guy like Greg Maddux who – at the same point in his throwing motion – is more flexed on the front knee, generally won’t have big issues in this regard (although they should still be assessed and addressed).
Leaving these issues unaddressed can lead to a host of problems, most notably hamstrings strains on the back leg.
3. Manuel Buitrago has put some excellent Olympic lifting demonstrations online to help those of you at home who are trying to pick up these complex lifts on your own. Here’s a little sample:
4. While I think it’s awesome that a lot of folks are finally catching on that glute activation is important for both injury prevention and rehabilitation, a lot of folks have lost sight of the fact that you have to be careful about just training the glutes in hip extension. It’s also very important to pay attention to theirs roles as external rotators and abductors. Once you’ve mastered bilateral movements in the sagittal plane (e.g., supine bridges), you need to get into single-leg and emphasis movements like bowler squats and lunges with reaches to various positions. These are great inclusions in the warm-up, and we highlight several options in our Magnificent Mobility DVD.
And, to take it a step further, you’ve got to load up those single-leg movements and challenge frontal plane stability to lay some strength down on top of those newly discovered movement strategies.
5. In light of the flexibility/mobility tone of this series of random thoughts, I thought it might be a good time to remind you that “creep” typically sets in at about 20 minutes. So, if you’ve been sitting at your desk reading for longer than that, it’d probably be a good idea to stand up for a few minutes, Quasimodo.

Any chance of some future blog posts and/or newsletter coverage on when and how you use goniometry in your client evaluations as well as recommended resources for learning more about goniometry? It would also be interesting to see you devote some coverage to the topic of how you go about assessing mobility versus stability issues to ensure that you’re not treating a mobility issue with a stability strategy or vice versa.
