Hello so i was going to the gym for about two years, now and had a nice progression , but recently started to train MMA and really liked it, lots of people say i will lose muscle or i should not train in gym anymore , so how to change mindset so that, I wont be worying about losing muscle or size and just train mma .I still wanna go to the gym maybe one or two times per week , sounds stupid but would really help. maybe someone have lived trough the same .
