Great Question HappyPuppyF.
Martial realists don’t have to cross train. You could only train in one style all your life and be a realist when it comes to your training.
The difference is that “reality based” artists use different tools and diffent criteria than “nonrealists”.
For one, the scenarios are entirely different. Reality based training puts you in a dissadvantageous situtation from the start. Multiple attackers, weapons, unknown positions, etc. A good reality based program will test and train their students in differing environments with natural obstacles.
Instead, nonrealists train duel style. If there are multiple attackers or weapons the trainee knows where they are, and what they will be doing.
Also, the criteria for judging a good technique for a martial realist is, “Could I make this worked in the street?” Not has someone else made it work and taught it to me, or someone told me it would work. Big difference.
As for sparring, reality based schools use sparring as a laboratory as well as a testing ground. Nonreality schools use sparring as only a testing ground for already learned techniques. The reality based schools are interested in “tinkering” with new technques all the time. The only place to test if they work before trying them on the street is through hard sparring. The nonreality school is testing the individual, already assuming the learned technique is valid. The reality based school is testing the technique as well, not assuming it will work at all.
And finally, the reality based schools almost exclusively have one primary goal in mind, to make people better fighters. Contrast this with the goal of making someone a better karateka, judoka, wrestler, striker, etc. Again, big difference. And also the reason why so many reality based schools cross train.

If you pr!ck us, do we not bleed? If you poison us, do we not die? And if you wrong us, shall we not revenge? If we are like you in the rest, we will resemble you in that the villany you teach me, I will execute, and it shall go hard but I will better the instruction. MOV
