Bit of a long personal story here. 3 months ago I tested for my 3rd dan, 1st gup. At my school, we have intermediate tests between dan ranks. I'll need a total of 4 gups to be eligible for my 4th dan. Near the beginning of my test, I gassed out. I almost threw up. I almost gave up. I felt sick the rest of the test and I was miserable the entire time. I gassed out during our kicking testing. We have 22 kicking combinations. In those 22 combinations are a total of 25 regular kicks, 10 spinning kicks, 29 jumping kicks, and 11 punches. We do each combination anywhere from 6-12 times during the test. That means I was doing probably somewhere in the realm of 600-800 kicks, with a lot of jumps and spins. I got tired. I made it a goal that weekend to stop consuming processed sugar, and to start hitting the gym so I could get in cardio and resistance training. I was pretty consistent about hitting the gym for a couple months, but then I got sick. I'm working on getting back into it. However, I have been consistent about the sugar. No more... Soda or juice (only water and milk) Syrupy breakfasts like pancakes or waffles Sugary breakfasts like donuts and cinnamon roles Desserts like cake, pies, cookies, chocolate, candy, or brownies (instead I eat a lot of fruit now) Before, I was consuming probably 2-3 liters of soda per day, and probably 4-6 servings of dessert-like food. I figure I've cut around 1200-1500 calories of sugar out of my diet, and that's including adding back in the sugar I get from fruit. In my work clothes, my belt had been feeling tight on the 3rd notch. It's now incredibly loose even on the smallest notch. My clothes are so baggy they don't feel right when I wear them anymore. I may need to go shopping soon. In Taekwondo, I notice the difference by the frayed part of my belt outside the knot. There's a good 2-3 inches on either tail of the belt that is frayed from where it used to be part of the knot. Oh, and those extra couple inches on my belt? Made it long enough to smack myself in the face when I was practicing Taegeuk #2 today. At this rate, I'm gonna need to order a smaller belt in a couple months.
