Students studying to achieve the Purple Belt ranking focus primarily on learning to block using the legs. Various blocking maneuvers using virtually every part of the leg are studied throughout the Purple Belt curriculum.
Students should keep in mind that blocking actions can have multiple purposes. The first and most elementary, of course, is to use one part of your body to prevent a strike from contacting a more vital area of your body. But the same motion can be used, with some slight reposition of your location or center, to disrupt the opponent’s structure, parry the incoming attack, or otherwise manipulate the opponent.
Leg blocks are generally most effective at close range. So you will either need to be at close range initially or you will want to move closer as the attack is being initiated. This is not to say that leg blocks are ineffective or useless at a greater distance, but rather to say they will often work better if you impact the attacking appendage earlier or closer to the attacker’s body.
When practicing blocks experiment with using them at several distances. Sometimes work in close and at other times just at the outside range of the opponent. It is important to practice at all of these distances because you never know when or how an opponent might try to attack. Having experience at all distances and with all manner of attack will make your leg blocks more effective when you need to rely upon them.
