Too much focus on flexibility: Personally I believe this is where many people go wrong. My advice is to first and fore mostly develop form and strength, and SLOWLY build up flexibility to increase range of motion. Aim to have perfect gedan and chudan traditional keriwaza in slow motion and with maximum speed. If effective TRADITIONAL jodan techniques are not possible, just forget them! What I mean by `traditional keriwaza’ are kicks which travel a high path and smash upward, downward or directly into/onto the opponent with effective weapons i.e. – mawashi-geri coming down with josokutei (the ball of the foot) or sune (the shin); ushiromawashi-geri with kakato (the heel) etc.
If you are interested in actual stretching methods or ways to improve you kicks, please do some searches here on my blog via the search engine at the top left corner of the page.
