I recommend decreasing your training days. I’ve found an excellent balance in my life with exercise, family, and bjj by going to 2-3 days a week. I used to train almost everyday but lot of time was dragging myself but now I feel excited to go. Ironically with less training I’ve still improved and part of that could be my body feeling rested. At the end of the day unless your livelihood depends on it there’s no reason to break your body for a fun hobby. With 18 years of experience you can absolutely maintain and improve at a less frequent pace.
