Basically, im the smallest guy in my gym heightwise and in weight. Im 16 about 5'6 and 117lbs and the person closest to my weight is 140. Ive only been grappling for 8 months no gi and 4 months of gi. I won the arizona bjj open at 126 lbs after only 1 month of training, took 3rd in no-gi at grapplers quest in vegas on dec 1 after 3 months of training, and then again on may 3rd but i also won my division in BJJ. My only problem is my takedowns. I find it hard to do takedowns correctly since most of the guys i roll with outweight me by a ton. Ive thought about buying a grappling dummy but decided not too and out of the two matches ive lost, its because of the 2 takedown points... Anyone have any advice on other ways to practice takedowns?
