Does your sport involve rotation?
If you answered no, I would like to ask for a permission to prove you wrong.
Why such an overly confident attitude about the issue?
Probably because pretty much every human activity involves rotation in some level. Most of the sports certainly do. Running is rotation, throwing is rotation, hopping is rotation, catching is rotation, kicking is rotation and so on...
Training the component of rotation is crucial as is of course the ability to eliminate rotation at times.
Here are three rotational movements perfomed in a cable column:
1. As part of a comprehensive dynamic warm-up sequence
2. As part of a strength and conditioning program (with heavier loads)
Life is a rotational activity!
PS: Remember to do both sides (left and right) so that you won't be walking in a circle post-workout :-)
