This show is a bit "older" (2007-2008) but it is fantastic. It's very similar to the Human Weapon series but it seems to capture a bit more intensity than the Human Weapon does.
Basically these two guys travel the world learning all of these martial arts from some of the best practitioners in the world. They have 5 days to learn the style and then they fight against one of the practitioners. It is pretty crazy at times. My favourite so far has been the Krav Maga one (obviously) but I also liked the Kali (Escrima) and the Hapkido.
These are the martial arts that they covered. Some of the them can be found on youtube (type in Fight Quest) but it is also on NetFlix.
The strength trainee says "Why sacrifice intensity when I can sacrifice volume"

"We are not sport, when there is a sport issue, we are not so good. The boxer is much better than us at boxing. But he will have to protect his balls if he wants to punch us."
