I've recently decided to take a "break" from taekwondo after five years of training.
Due to stress from school (11th grade), I have been training less and less over the past five months, going from two lessons a week to maybe once a fortnight. I was an assistant instructor, and used to teach the younger students. I thought that it was irresponsible of me to be constantly absent from class and thus have decided to leave until I have freed up my schedule.
Is it possible for me to stay "in shape" for at least three months without attending any training sessions? I can practice for maybe half an hour on most mornings, so any short routine recommendations would be greatly appreciated.
(AN: I really like this answer, but I'm looking for something more specific to ITF taekwondo and around 1st dan level).
