Back kick

In the back kick, the leg is chambered the same as for the spinning back kick, but the hips are rotated less than 90 and the front of the body is concealed during and after execution. The back kick and spinning back kick offer many advantages over the spinning side kick without sacrificing power or simplicity. The spinning back kick, used most commonly as a follow-up attack in a combination, is safer because it exposes the upper body and head to the opponent less than the spinning side kick. In a properly executed spinning back kick, your back is turned to the opponent and your upper body out of counterattacking range. Timing and accuracy are essential. If you kick too late or too early and miss your intended target, your opponent may take advantage of your awkward body position to counter with a roundhouse kick to your face or kidney, knocking you down. If, however, you time your kick precisely, the spinning back kick is a devastatingly powerful kick.
The back kick, on the other hand, is even more powerful and faster than either of the other kicks. Because you don't actually spin your body, you cut the kicking time almost in half. To execute a back kick, slightly rotate your hips and pivot your front foot while quickly shooting your rear leg out under you to the target. The chambering position for the back kick is almost nonexistent because the leg moves so quickly to its target. In attacking, your entire body weight must be shifted into the opponent's body with your upper torso perpendicular to the ground when the kick reaches its full extension. When used for close range counterattacking, the back kick is an excellent tool for scoring against an aggressive opponent. To launch an effective counterattack against a roundhouse kick, for example, your back kick should be short, with less commitment of your body weight and more emphasis on speedy execution and retraction.

A spinning heel kick is performed from a low side stance. Beginning with a pivot of the hips, the rear leg is swung around the body between waist and shoulder height, striking the opponent's body with the back of the heel. When done correctly, the spinning heel kick is a powerful kick. However, it is also cumbersome, since the kicking leg remains straight from beginning to end.

An improvement on the spinning heel kick, soon came in the form of the spinning hook kick. A faster and more deceptive kick, the spinning hook kick eliminated the weakness of the spinning heel kick without sacrificing much in the way of power. A spinning hook kick is performed from a standard fighting stance and begins with a pivot and leg chamber similar to the spinning side kick. From the chamber position, the kicking leg swings toward the target and uses the knee to hook across the target on impact. Because the leg is chambered high, the spinning hook kick can be used to effectively attack the head, an almost impossible attack with the spinning heel kick.

To perform a spinning whip kick, begin from a short fighting stance (feet about one shoulder width apart) with your head and upper body aligned. Pivot your front foot in the direction of your target until your heel is pointing directly at the target. Bring the foot of your kicking leg up to your other knee to chamber the kick. Once chambered, shoot your kicking leg out toward the target, with your leg reaching its full extension about one foot to the side of the target. When your leg is fully extended, whip it across the target and return to your original fighting stance.

Many people will say that this sounds identical to the spinning hook kick but there are a few key differences. The first is that the spinning whip kick does not use a turn of the body to chamber the leg, but instead coils the body prior to kicking. When you pivot your front leg, your body should essentially remain behind and coil, like a golfer preparing to swing. This creates what is scientifically termed potential energy, a reserve of energy ready to be used. When you shoot your leg out to kick, your body's uncoiling force, not your leg's power, delivers the blow. This brings us to another essential difference between the two kicks. The spinning whip kick uses the power of the entire body, not the hooking force of the leg, to create power. By turning the body into an uncoiling whip (hence the name of the kick), it allows even the smallest competitors to deliver knockout blows.

A final difference between the kicks lies in the positioning of the upper body during the kick. When performing a spinning hook kick, the body moves forward toward the target as the turn is made (before kicking) to chamber the leg high enough. The spinning whip kick coils the body in place instead, creating a static axis around which the leg moves. A static axis provides the kicker with many benefits including better balance, more power using less muscle force, more speed, and quicker response time. It also means that the kick can be executed from a very short distance, allowing counterattacks to the head while your opponent is moving at you. The spinning whip kick is often modified in competition, with the kicker dropping his head out of range of a counterattack while he is kicking. This is an advanced strategy that should be practiced only after you understand the dynamics of the a correctly executed spinning whip kick. If you try dropping your head without understanding the purpose of this movement, you will find it difficult to maintain your balance, speed and power throughout the kick.
