Once you are cleared from your Dr. to get back into the gym then we will work on flexibility of the affected area, stretching of the muscles, increasing blood flow to the area, strengthening the surrounding muscles of the area, and then once that is done we can work directly on the affected area. Depending on the injury it can take a few weeks to a few months to bring it back. Example, the client I had who came to me after suffering a broken neck, it took about 5 months before we could focus on the direct muscles and once that was done it took just over 3 months to get him into shape. Whereas the other client who came to me with a broken back it took us 3 months to develop and strengthen the surrounding muscles and get flexibility in the target area and within 5 months they were able to hit their goal. It really all depends on what the injury is and how bad it was.
