I love grappling and martial arts in general, but being in school and working a lot of hours, I usually don't have that much free time to workout. Just getting to the closest BJJ/Mma gyms usually knock an hour off my day(roundtrip). In the summer I usually travel as well, so with all things in consideration, I need a gym where I can pay monthly and not have to commit to a year membership from the getgo. There are some months where I just won't be able to train(exam months, long vacations). Most good gyms I've ran into so far make you pay your membership in whole immediately which sucks. So I've been wondering, is this a common thing? Do your gyms also do that? I understand it's most likely better for them financially, it's just not convenient for my busy lifestyle.
