BJJ at 40.... Why?The IBJJF defines 36-40 year old competitors as senior. No other area of society, other than sports, are young men and women referred to as seniors. Most would agree that 40-year-olds are middle aged, but not senior. The 20’s are the new teens, the 30’s the new 20’s, and the 40’s the new 30’s. There have been many athletes to accomplish great things beyond 40-years-old. Former NFL player and current BJJ brown belt Jarrod Bunch has won gold medals in the 18-29 division of IBJJF tournaments.
