I took a picture from Phil in 2012 and analyzed some key points that can be used to compare his muscles to that of a person who used to exercise regularly.
This is not the body of a person who was ever athletic, this is the body of a person who has never had a developed muscular frame. Also notice his chicken legs.
Anyway, here's the recent photo everyone brings up from his Halloween DSP tries it, where he looks fucking awful.
He definitely looks much worse than before, and in only 6 years. He doesn't even have the semi healthy-looking fat deposits he used to have, now it's all manboobs and stomach, where it used to be manboobs and stomach and a little bit more in his neck and back. Anyway, all I'm trying to say is that a.) he's never been muscular or strong, which is clear from the poor frame he's had since he was young. Even his youngest pictures (him at fighting game tourneys), he's skinny as shit. All he did as he got older was get fatter, and now he's just getting sickly-looking.
