* This concludes my preparatory exercises. Following this, one’s body and mind will be well prepared for karate-do training. I would just like to end with a couple of tips. Firstly, stretching should not be painful, it should be a stretch; therefore, take your time and listen to your body. Secondly, try to warm up in comfortable environment, ideally not freezing cold (but, if in cold environment, such as participating in kangeiko, increase the aerobic portion of your preparatory exercises). In my case, here in Aso-shi, unfortunately this is not an option; consequently, it is a case of simply soldiering on... Third and lastly, pertaining to point one, don't compete with others, nor yourself. Some days, perhaps you will be stiff and sore, others you may feel very loose. The preparatory exercises are just that, preparation for training, they are not a measure of your self-improvement or ability in relation to others in your dojo. Injuring yourself because of "overdoing it", during you preparatory exercises, is clearly not smart. Relax, breath, and work according to your daily condition.
Conclusion: I wish you the best of luck in your karate-do training; moreover, that you maintain a healthy body whilst practicing with vigor. On the whole, it is irrefutable that safe, and effective, junbi-undo/taiso is paramount in the on-going advancement of karate-do skills.
