Do you want be "magulang" over your opponents? Do you want to one-up the other guy? Here's how: 1. 1 week before the competition, train vigorously until you work up a good sweat. After training, keep your gi in a warm dark place. 2. The day after do some calisthenics with the same gi. After training, keep your gi in the same place. 3. The day after, go lift some weights in the SAME gi. Return it to the same place you stash it after trainin. 4. Go to your dojo and train vigorously with the SAME gi. Repeat the drill. 5. Take a rest until the day the competion. 6. DO NOT BATHE 24 HOURS BEFORE THE COMPETITION! Nobody will be able to stand against you at the actual contest. Newaza much preferred.
