I have a bjj tournament coming up next sunday. I'm going to be fighting in the heavy division which is 207.5 with your gi on. Right now I just weighed in at 213. I want to lose 10 pounds to cover myself for my weight with the gi on. I basically signed up on short notice and havent been dieting or really doing cardio like i should, so basically i need a quick way to make weight.. i have until next sunday. Any tips would be greatly appreciated
