I'm 5'7 172 lbs. with gi on 176. I'm trying to determine the best weight to walk around and compete in considering my height. When I started BJJ, I weighed about 195. At my last competition I competed at middleweight whitebelt senior1. By the third match, I felt sluggish. I also noticed that some of the guys in that weight range are taller than me. One factor to consider is that I'm a police officer and I need to be able to handle myself, i.e. strength and stamina. My concern is that if I drop to far my strength may suffer. I'm thinking that I should probably be around 160 for future tournaments and on a daily basis. Any advice would be appreciated.
