There was a guy that i trained with for a few months that was about 6'2" and weighed 350lbs (i'm 5"8/170)... we were practicing some throws/takedowns and i showed him a defence to a bear hug but the problem was that my arms were not long enough to fully wrap around his waist.
when we rolled, i managed to get the mount a few times but his gut was so big that my knees wouldn't touch the ground, nor could i really hook his legs. it was very hard for me to keep him there without him just bench pressing me away. when he was in my guard it was near impossble to do anything, i couldn't sweep him, my legs weren't long enough to get a tight triangle, he had a huge neck which was hard to get my arm around and he was too bloody strong to do anything with his arms. the only way i'd beat him is by waiting 5 minutes until he had no energy and gave up.
