When I first started BJJ, I found out really quickly about the need to wear a cup. With all that thrashing around, it doesn't take much for "knee on stomach" mount to become "knee on junk"
I have noticed a trend though. More and more fellows at my school are wearing headgear(plastic ones that protect the ears)and mouthguards.
I have been to a couple of BJJ competitons in the last 6 months. As a spectator. I have not noticed anyone in the competitons wearing headgear or mouthguards.
Is it really necessary in training? Are they forbidden by rules in contests? For my long term protection should I invest in both?
Any responses are appreciated.
