Phil Heath from AC joint to wrist is a genetic freak in terms of muscle shape, muscle density and muscle belly length, period! The rest of him is good too. Now, to suggest that he is somehow doing more or less because of his genetics, well no he is doing what all the rest are doing.(more or less) I would call his genetic respond to hormones on a scale for example (Excellent. 5. Good. 4. Satisfactory. 3. Fair. 2. Poor. 1) I give him a 4 which is good. I would give Ronnie a 5 if he were human, but he is not so this scale does not aplly to him.
