Conclusion

The amount of progress you will make depends upon the amount of effort you put into your judo. Obviously going to the judo club once a week will not get you along as fast as you would if you went three times a week. It is possible for a young man to get his black belt within a year providing he starts under the right instructor and trains really hard. However hard you do decide to train, I'm sure that you will enjoy judo. I have been doing judo for thirteen full years and I still manage to learn something new about this intricate sport every time I go on the mat. I wish you luck in your efforts.
