I am training to go into an exhibition fight in December, and while it is a long ways away, I have only been training in Muay Thai for about 6-8 months. My techniques are improving, but I want to be able to combat my back pain. It is not as bad as it use to be and was caused due to weight lifting. I am trying to gain power, gain some muscle mass, and also improve my technique. Any thing I can do outside of training hours to strengthen my back so I do not experience any worsening of pain to my back? Has anyone personally experienced this? What is the best option for this?
