Yesterday I saw a video on what was classified as 'Knee Dominant' exercises. Of the four or five that were presented, two of them were not actually knee dominant at all!
What was even more amazing was that the athlete in the video was loaded with a substantial amount of weight while performing a single leg squat. However, the fact that the athlete could actually perform the rep was not the amazing part. Yes it displays a great amount of strength, but performance based strength is not about the amount of load. It is about generating TORQUE! (more on this topic in a future post)
This is why it is so important for coaches, trainers, and therapists to understand basic concepts of biomechanics. For example, performing a single leg squat off of a box while driving both arms in front of the body as well as the non-loaded leg is not a knee dominant exercise after all. In fact, it is a hip dominant exercise due to position of the center of mass.
Classification of exercises is critical as they have a huge impact on program design!
