Hello Tom!
Most of definition is in your diet! Cut out as much sugar as possible, as well as things that the body converts to sugar rapidly such as white bread, pasta, corn, rice, etc. Whatever sugar is not burned for energy will be stored as fat! Also, for the last set of each weight exercise that you do, cut the weight approximately in half and do speed reps (as fast as you can go while still keeping good form) to complete failure! That will not only help with definition, but also with your explosiveness in your martial arts movements! Finally, cardio helps tremendously with muscle definition. Do cardio at least every other day (if not at least some every day). Also, if you aren't already, you might want to take some kind of fat burning supplement to increase your body's ability to burn fat and speed up your metabolism a bit! Slow metabolism is one of the greatest causes of lack of muscular definition! Hope this helps!

Keep Blasting!
