I think Jay is struggling with the fact that Bumstead has become the face of the fitness world. Iain and a few others have hinted what Chris is making and it’s staggering. He’s clearly jealous about being replaced.
Jay is constantly getting new cars, reminding everyone how good he was with the rehashed old pics on social media, the “I’m gonna get in the best shape ever at 50”, interviews about how much money he makes, I’m going house shopping vids (the model home in the new vid is open for anyone to see btw, it’s right by the airport, he just did the vid for attention), the ridiculous YoungLA endorsement, etc.
