You are not expected to kick perfectly yet. For now, be sure and learn to feel how left arm works with the right leg (and vice versa). In other words, your left arm comes towards your right leg, and it should occur automatically. As soon as you are comfortable with this, it is a sign all the parts between the arm and the leg are involved. At that point, you can progress to the next drill.
Spine Part of Kick
During the top hop, the weight of the body is transferred into a sort of tucking of the tail. During the kick, the same thing happens except one foot is in front.
Kick Front Leg
If you were able to perform the initial kick properly, you can be assured that the three links of the chain in the kick are all functioning. The next stage of development is for the links to work not simultaneously anymore, but instead in a sequence. First comes the front leg, then the torso, then the back leg. By clarifying the front leg, and even emphasizing the front leg, you will soon be able to initiate the movement with the front leg because in your brain the front leg will become represented by its’ own button.
Kick Spine Only
What we are doing here is isolating the torso, and having it do the kick.
The hip of the back leg in all poor kickers (and therefor poor runners, etc) is always active prematurely . So while the front leg is important to strengthen, the key to the back leg is actually to learn to wait before bringing it forward.

Eccentric Kick: (anticipation of kick: Mid-brain/initial cortex connection)
Each individual button developed during the sequential drills has to be connected to the midbrain. During the initial kick, you created a button on your brain that, when pushed, caused you to kick. When moving to the sequential part, that one button separated into three buttons (front leg, torso, back leg). Each of buttons you created needs to be controlled, and during the eccentric drills you are developing a dimmer switch on each of those buttons). These drills are subtle and very important. If you were teach a child to shoot a sling-shot, the important part is how far back you pull. Letting go is very easy if you can control the tension properly. The eccentric drills teach you to the control the stretch so that the actual kick happens automatically.
Kick Torso Eccentric
During the kick, the arm joins the opposite leg, which contracts some muscles in the front of the torso. Prior to that, however, those same muscles are stretched. If you can simply feel some muscles in the abdomen contract as the arm and leg move away from each other, you got it.
