So i had a tournament last year in October after about 8 or 9 months of training. I ended up losing both matches. The first match i was proud of myself because i did some excellent reversals and what not, i simply got caught within the last minute or two in a guillotine which i had escaped earlier in the round (The first one really took alot out of me.) Anyways i decided to fight at the top of the 169.9 bracket meaning i had to cut around 5-6 pounds in two weeks. The way i did it was simply eating small meals (i remember being hungry during the night but i don't ever remember being completely drained or anything) and doing the normal rolling in class and working out after. I ended up weighing in at 169.7 or something like that. Did i cut wrong and mess up any cardio i had or was what i did an okay thing?
It sounds like you cut weight properly. However, rolling in class and having an actual match in a tournament are two different experiences. You have to remember that at tournament time your adrenaline levels will be raised, an you'll wind up expending more energy doing seemingly the same movements. Just try to relax and go with the flow, and the tournament victories will come.
I am have that same problem right now. i have a tournament in a week at 155lbs. i weighed 160lbs. because i have never cut weight.. or needed to diet (in fact.. i always thought i had trouble putting on weight).. i didnt really know what to do. i ate a lot less. and because of that.. did not have the energy to work out as much as i used to. hopefully it wont affect me... we'll see
