I've never heard of anyone on about this in BJJ. Well i was going to enter the Brittish Open but sadly didnt but before hand i asked my trainer if i should cut down from 75KG down to 68KG for the competition but he said "You'll be fine" but i noticed that most the competitors where roughly the same size and build as me when watching the tournement. I cut from 76KG to 72KG in 3 days for the Ground Control competition (No transport FTL). So is cutting weight big part of BJJ in competitons and in general?? Sooner or later i will have to get use to cutting weight for MMA fights but will i have to do the same if i wanna do well in BJJ competitons?
