Hi... If you have any back or neck problem like pain, numbness, vertigo etc, you should be doing the specific exercises for your spine first. Once those problems get solved, which generally get solved in a short period of time, you will be able to do all the exercises. e.g. Weight training, Yoga, Running, Swimming etc etc. There won't be any problem. Have a happy healing... ☺
