I strongly believe in supplementing karate traininig with free weight training and aerobic fitness training. Keeping an exercise diary is a great way to stay objective about your workouts and helps in identifying areas that you may be neglecting.
I have found a very simple, but effective diary available to download for free at topshareware.com. After installing it open the program and click the “setup” tab in the lower left corner of the window. Then click on “exercise”. At the bottom of this list is a blank tab where you can enter whatever you would like. I have added “kata”, “makiwara”, “heavy bag”, “jump rope”, “chishi”, etc to mine. The set up is pretty intuitive and I have not had any problems.
