I train 3 days a week. I stretch for 30 minutes each morning. On my non-training days, I run 5 miles or ride an exercise bike for 30 minutes. I force myself to lift weights one day a week. But, to be honest, I HATE it. For me, it is so boring. How necessary is weight lifting in your opinion for staying fit and not injured? Is it worth the time for you? P.S. Just trying to get a sanity check. I am not a competitor. My goal is to keep training and gradually get better over time at BJJ.
