how many hours per week do you train?

hey guys, i just finished my 2nd class of Muay Thai. absolutely love it, it's really fun. I'm curious as to how long your guy's classes are? and how many hours per week/day do you train?

the classes for my gym is an hour. maybe 2-4 minutes of simple warm ups and stretching, then the rest of the time is pad work and technique. (my gym doesn't have any bags yet - it only recently opened up)

Im planning on going 3x a week. I'm also doing powerlifting. is there anything else I should be doing outside of my classes to be better at MT? (aside from lots of stretching) or is just an hour of MT enough for someone who is new at martial arts and just beginning?
