Sanshou fighting and full contact fighting

Once again, I love new training exercises and traditional exercises to make me a better fighter, does any body have any info on traditional full contact drills in southern styles(Hung Gar, Wing Chun, etc.) I like drills that toughen the body and increase stamina, muscular endurance, and pain tolerance for full contact. Any drill and or info is appreciated.

-A fighter with no foundation is an inefficient fighter

Practice three star blocking (arm smashing), but careful not to injure yourself.

You can also make creative drills with a partner, or a tree, or a tire, or whatever is at hand. If you have a partner, try simple attacks and defenses. Practice these over and over and over again.

These are just some absolute basics, but very very useful.
