Greg and I had a great conversation at band camp once... Well not band camp but his CA Coaching Certification and the jist of it was simple. Do you want to be a weightlifter who does BJJ or BJJ player who athletically lifts weight?
It is hard to be all things all the time. I personally am a lot older and will go through periods of really hard BJJ with less lifting and heavier lifting with less BJJ.
No real answer here just a thought starter. Ultimately you should do what your body can handle. If you can handle heavier lifting and the training you need to become the martial artist you want go for it. If you do it and crash you might need to revisit the schedule.
Best of luck, BJJ is a great sport.
