If you have a friend who studies karate, ask that person to explain to you what the classes are like.
How much repetitive training is involved?
Does the sensei (instructor) expect the students to practice often on their own?
Call a local karate or other martial arts school and ask if you can observe a class.
Can you see how karate practice trains both mind and body?
Think of some skill that has taken you a long time to learn.
How did you learn it?
Were you training your mind or your body or both?
Do you still need to practice it to keep up your skill?
Write down your answers and compare results with those of your classmates.
Which types of skills require frequent practice?
Karate practitioners develop thickened skin, or calluses, on their hands from practicing strikes on pads and straw-covered posts called makiwara.
Notice which areas on your body have calluses.
Do you know how you got them?
Figure out what purpose they serve at each spot.
