I didn't see anything happen at 3:25, except he leaned back and resumed back 'relaxed.' But, as the image above shows, I saw that stick out of his gut around 3:38...very odd. Maybe cramping and/or muscle spasms due to low fluids/diuretics?
And just before that, I was watching him and thinking "that is how I want my midsection to look."
I'd still take that body any day over someone like Ruhl.
