Classes are finished for the day. I am reminded that there are more variations on stretching techniques than there will ever be time to practice consistently. Then again, this is true of technique variations of all kinds. Hand techniques, foot techniques, weapons techniques, chin na, shuai jiao… Even movements within forms can have many correct variations.
Since there will never be enough time to practice everything all the time, it becomes more and more important to practice specific things daily for the cumulative effect of repetition over time. Those things must be chosen wisely to strengthen points of talent, to round out rough edges in the training, and to buff up weak points of technique or poor understanding of difficult concepts.
Choose carefully and train every day.
