So back story I trained bjj for years and was blue belt. Took a 9yr break. I started doing MT and love it.ive been doing MT for a year. I feel like I should also train im BJJ. But I have no drive to anymore, and just want to do MT. Im also 31 now and kinda worried about injuries in bjj. Idk maybe Im nervous or my ego is saying I wont be as good anymore in bjj. I guess my question is how many of you trained ground fighting and then decided striking was better for you? What are your reasons for not crosstraining.
