I find it difficult to understand why there is still so many different opinions from the medical community pertaining to weight lifting post operation. Although I never approached weight lifting to the extent of body building like Arnold has, I have lifted weights since I was 15 for sports-related training. I started lifting again four months after my surgery and I feel fine when performing the exercises. Although I don't "max-out" or lift to failure anymore, I still think the benefits, outweigh any perceived risks. My cardiologist is OK with it and when I asked him directly last week during my 6-month post-op session, he told me there is no risk to the heart or the valve in peforming such exercises. He did indicate, as with any physical activity, moderation is the best approach, with which I agree 100%.
