Using a combination of ideas won't necessarily help you understand what works best for you. Studies show that when it comes to chronic back pain, doing something (anything) is better than doing nothing. But doing everything at once isn't always better than consistently following a single approach.
If you are experiencing increased back pain or boredom with the program, then it may be time to look for another treatment idea. Other medical problems and psychosocial problems can get in the way and set you back. It's important to keep going even when improvements seem small and progress is slow.
