    Purpose of coil in the rear hip.

    As suggested I started a new thread. Here is the question I posed:

    I'm curious what coaches on here think the purpose of this coil/uncoil in the rear hip is, regardless of how we describe the movement. Is it the primary power source? Is it a vital secondary power source? Is it just to aid in timing? Does it help transfer the energy more efficiently in the kinetic chain? Does it give the hips a running start? Or is it a combination of two or more of these?

    It's the first step in making the lower body provide power. It helps get the lower body running start, though another action is needed to do so. It can aid in timing, though I don't usually think of it as doing that. It can aid in timing because it forces the hitter to "stay back". And, it allows the energy to be transmitted more efficiently.

    Turning the hips- with the hips is slow. Having the hip being turned by the leg is quick. I like to think of the difference between the two like this: If I stretch a rubber band, and then release it from that stretched position, it's going to fly further. That's turning the hip with the leg. Conversely, if I stretch the rubber band, lose the stretch, and then try to release it (by throwing it or something like that), it won't fly as far. Also, if I fail to use the stretch, why did I stretch it in the first place?

    This isn't a great analogy in terms of how the body works, because human tissue is far less elastic, but it's a good visual aid.

    P.S.: I'd like to add that the correct terminology is coiling "around" the rear hip. Coiling "into" the rear hip doesn't create the same movements.

    The front foot must be down when the ball is roughly half way, so how would this impact timing?

    Just because the foot is down doesn't mean it's weighted. I tried this with a scale once (while coiling) and I found the distribution to be roughly 75-25 when the front foot is down. However, it feels like all of the weight is on the back leg.

    BTW do you think that the coil should be into the back leg or around the back leg? I have heard both.
    I think walks are overrated unless you can run. If you get a walk and put the pitcher in a stretch, that helps, but the guy who walks and cant run, most of the time hes clogging up the bases for somebody who can run. Dusty Baker.

    Around, though the majority of people don't distinguish between "into" and "around". Into is BAD, around is good.

    The coil is how you get your weight back. The uncoil is how you shift your weight into the pitch. The pelvis gets turned back so it can be turned forward into the pitch. It's a move - counter move...First back then forward. It's the primary power source. Without proper pelvis action you are strictly an arms and wrist hitter.

    I don't understand 'around'. I've seen it mentioned before, seen pics, but I'm still not sure I get it.

    Isn't this simply lunging vs rotation?

    Thanks.

    Around is the feel of turning the rear hip away from the pitcher as if you are pulling it around towards the dugout behind you. At the same time your back leg is turned in the other direction, inwardly. The around is a feel of only using the rear hip, the glutes, the low back etc, to pull the hip "around" and to resist with those body parts any leg drive forward.

    Encinitas is correct. It is not "lunging vs. rotation".

    Try this: get into an athletic stance, and turn your rear hip "around" the rear leg. Turn the toe in a bit to help. You should feel a bind in the hip socket. That's coiling "around".
