P90X is an extreme fitness program and should not be attempted by someone who has a history of knee, shoulder or spinal (back or neck) problems. This warning is not to be discounted. There are many fitness alternatives if you have weaknesses or are prone to injuries – but P90X is not one of them.

You may want to try looking into the Power 90 as it might be a better fit for you.
