More Power in Your Kicks
Straightening Your Standing Kicking Leg To get the maximum power in your kicking techniques both legs should be straight at moment of impact. Hopefully when you throw a kick you should be in a correct low fighting stance which means that both legs are bent. A lot of students straighten their kicking leg but do not straighten their standing leg resulting in lack of balance and reduced power.
The upward push needed to straighten the standing leg adds extra momentum to the kick results in maximum power. This extra power can be seen in all kicks but in particular in the execution of back kick.
Remember: Practice the technique very slowly at first and only when you are happy with your technique gradually add speed. Speed is always the last thing you add to a technique to try and perfect it. Adding speed too early can have negative effects on your technique, so take your time.
