Do you think it's possible to train in two martial arts at the same time?

I'm a 17-year-old guy who trained BJJ for a while as a kid and I want to get back into it. I plan to train seriously. The gym I'm considering also offers Muay Thai, which I've always wanted to do but couldn't as a child. They also have alternating days: BJJ on Mondays and Wednesdays, and Muay Thai on Tuesdays and Thursdays. The cost doesn't change much because the gym includes all activities when you sign up for a membership. Do you think it's possible to do both?
