Front Kick and Front Line Kicks: Technical Kicking Leg Development

This is the program that develops the kicking leg of the front line kicks. Here is a more in depth explanation.

This program is aimed at two things

In simple terms:

  1. flexibility in the back of the leg, and
  2. strength in the front of the leg.

When it comes to elasticity and general strength to perform a kick correctly, all front line kicks share the same strength/flexibility requirements.

(Front Line Kicks Being: All Variations of the Front Kick, Axe Kick, Inside Crescent Kick, and Outside Crescent Kick)

Don’t confuse strength to do the kick properly and kicking power.

To understand this concept let’s compare punching and kicking. General strength is needed to extend the straight punch and hold it to the opponent face and power is to actual punch with force. It’s important to understand this distinction. Since technical strength and power are different things.

Strength and Form

However, having the strength to do the kick correctly, will improve many aspects of the kick, including power. Front Kick is the most basic kick, and yet so few martial artists have a proper form. Knowing what the proper form looks like and producing it at will are completely different things.


To throw a kick properly, 15-35 degrees of hip flexion are needed extra, on top of what the intended kicking height requires. The reason in such a large range difference (15-35 is 20 degree difference) is due to the strength of the muscles that flex the hips.

The Stronger muscles that hold the leg up the less flexible one can be. The weaker a person in that area, the more flexible they need to be.

If the paragraph above is confusing, here it is in simpler terms. If you want to kick comfortably to the solar plexus, you need enough flexibility to kick to the face.

Here is a video explaining this in more depth:

This program is very short and to the point. It attacks both fronts.

  • Zaichik Stretching Technique develops flexibility.
  • Reciprocal Inhibition and Antagonist Short Range Conditioning develop strength.

Within the proper sequence of skills development, this program should precede other modalities of the kick: it comes before Endurance, Control, Accuracy, Speed, Power, etc.

Do you need this program?

  • Extend a front kick to your own head level. Hold it for a few seconds. If your body is straight, back is not curved forward, and you feel comfortable. You have enough strength and flexibility, and you don’t need this program.
  • If your back is hunched and/or your kick can’t be comfortably held at your head level even for a few seconds, you need the program.
