Maybe 5-6 pounds water weight you can put back on, I wrestled highschool and the sweat suits in the shower run with the hot handles turned to steam and then jumping jacks you can cut 2 maybe 3 lbs if you start early enough ,,,mostly 1-2 lbs realistically any more than that and you're pretty much steamed out yourself when you hit the mat, so if you wanna say 8 lbs heavier I'm of agreement, if you wanna say 15 lb. That's not a viable guesstimate, another thing 82,,, some of those guys were built and looked like shaved apes yet when they hit the scales they were legit,,,
