Ditto what copyman said.
The exercise part of bodybuilding is good for your liver, but you might want to think twice about doing a protein-heavy bodybuilder's diet. Too much protein can stress your liver.
You might want to talk to a doctor about what is the appropriate amount of protein intake.
the only way your liver count is going to lower is if you treat the HCV. hopefully you can hang in there until the new drugs come out in a few years. best of luck
