Here are some good old gung fu exercises I do:
Northern fists/southern legs.
Stand in a side nuetral stance, and punch out with your right hand. When you punch drop in a really low horse stance. You should not be much outside shoulder width with your feet (like 1 to 2 fists distance outside your shoulders). Tail bone is sinked and the spine is straight. Hold up your left hand in some sort of guard (pick your flavor of guarding hand). Hold the stance for a few seconds. Then slide the back foot (foot furthest from your punch) up into a smaller bow and arrow stance and punch with the left. Repeat over and over again. Do that for 30 minutes is a good work out. The lower u can keep your stances the better.
Snake creeping meadow/ hungry tiger
Drop down into a snake creeping meadow stance, hold it for a second, then shift all weight forward into a strong bow and arrow stance, and your hands now form tiger boxing techniques.
foot work exercise.
stand in a normal relaxed stance, drop into a low cross stance (knees almost touching the ground). With your front foot now rooted stand up straight and kick with your back foot, then step over with the opposite foot and repeat. Maintain a guard at all times, and switch your hands to coordinate with your feet.
Punching:
500 chain punches daily, if not more
Pivot punching
back fists (keep those tendons loose)
practice all elbow postures
Kicks:
500 kicks if not more
take a chair and circle kick over it, then crescent kick back over, repeat both sides
in a cat stance practice front, and side kicks with out rolling the hip over (compact the movement for effeciency)
If you got the room arial kick drop to sweep, jump up arial kick drop to sweep, repeat until tired.
A lot of this stuff I do, I would hardly use in real combat, I use this for training.
