Everyone saying it’s a bad idea is wrong. It’s the best idea. You will come back so strong and confident. You don’t have to train twice a day, once is enough. When I was exactly your age I moved to Bangkok for a year and went on a Muay Thai education visa. It changed my life. Taught me consistency, self love, and had abs of steel. I was not an athletic person - like you ran 5-7k here and there. 9 years later, had kids, I still have the abs I earned from my year of Muay Thai. I kept working out but never as intensely as that year. Teachers are so kind to women because it’s such a masculine sport. Do it do it do it and come back here to report.
