143 Incorporating rhythm breaks
Many riders are stuck in the fall line. Often this is the result of learning how to turn via heavy use of rotation and counter-rotation. Since rotational movements are typically of short duration, short turns are the only viable option. Usually these short turns are made with an excess of weight on the front foot. This is not particularly useful if you want to make a longer turn. Longer turns out of the fall line rely on accurate use of pressure distribution and movements onto and off of the edge of the board.
Another factor in riding mode is the means by which a board is brought to its edge, and the relative weight of the body parts doing the tipping. The heavier an object, the harder it is to move it quickly, or accurately. This is why many beginning riders tip over. They lean into the turns leading with head and shoulders. At their slow rate of travel, it does not take much to tip over. So, if a rider is turning a board with too much upper body movement, that will impose a limit on how versatile they are, with regard to turn shape and the ability to alter rhythm.
Usually, when the hips go one way, the shoulders go another, and vice versa. Hands and arms are often used to counterbalance erroneous movements of the hips. So, if a rider has difficulty changing the way they ride, the answer might be revealed in the obvious asymmetry of their outward appearance.
If a rider is effectively utilizing the edge and side-cut of the board, but is not able to make shorter turns, it may be that they are not using their feet to initiate their turns, but the knees, or hips. Again, smaller body parts move more quickly than large ones, with quick accurate movements one of the requirements for an effective short carved turn.
