A while back I posted a video of the Full Contact Russian Twist and alternatives and there arose some debate about the safety of twisting.
Vern Gambetta has put up a good post today about rotational movements:
Rotation is bad?
Let’s put this silly and absurd idea to rest immediately, rotational movement are not bad! Just like anything it is dependent on context, mode and where they are placed in the training program. Remember there are three cardinal planes of movement, sagittal, frontal and transverse and the body must be able to move through all three planes without restriction at will. A significant amount of force reduction against gravity occurs in the transverse plane, therefore to prevent injury avoiding rotational movements would be a huge mistake. Modes of exercise like medicine ball, kettle bell and stretch cords enable rotational movements to be trained in various patterns that can prepare the body for the demands in the specific sport or movement you are preparing for.
Remember a simple rule of thumb – you are what you train to be. You do not play in a phone booth, sport and life is ballistic, reactive moving though wide ranges of movement in demanding postures, don’t eliminate rotation build your program around rotation.
