Years of bad posture resulted in a twisted spine. I have a thoracic kyphosis and lumbar scoliosis. This has caused me chronic pain for the past 6 years. The pain fluctuates based on what I'm doing with my back. Standing for extended periods of time causes grief, as does repetitive bending and reaching motions. Martial arts training doesn't aggravate it too much, apart from the factor of standing on feet for a long time. I used to pick up barbells over twice my bodyweight, but I'm cautious of doing anything like that again.

I don't believe there is a right or wrong answer. For a serious martial artist, hojo undo is absolutely crucial. If you believe weight training is going to benefit you, then do it. Personally, I hurt my back and am unable to lift weights. I used to lift weights 3-4x a week religiously, but now I can't pick up a barbell equal to my bodyweight without severe pain. Nowadays I do calisthenics. 500 pushups a day on knuckles isn't unusual. I do alot of pull-ups, crunches, squats. I train my grip and run multiple times a week. The most important thing is that you're doing something.
