Hello I have trained martial arts on and off for 8 years. I have obtained green belt in tae Kwon do, but haven't trained in a year. The last school I attended would only offer me a one year contract at $125 per month, even though I told them I travel frequently. I am usually gone for a month and home for 2 months, then repeat. It didn't work out for me at the last school so I am looking for a new place. How can I find a school that will allow me to train and progress, while being gone for work every 3rd month? I don't want to train at a mcdojo, but every legitimate school I've talked to wants to start me over at white belt and lock me into a long term contract. When I was younger, I started and stopped at many schools. I'm pretty efficient at all of the forms, kicks and punches up until blue belt level, so I feel it's redundant to keep starting over at white belt. When I explain to any instructor my work schedule, they never seem to listen. They just try to give me a long term contract and start me over at white belt. Any suggestions?
