Into Exercises With A Trainer .. Trying Particularly Get Rid

Into exercises with a Trainer .. trying particularly get rid of fat on abdomen 73 yrs old 5'11". 190 lbs. should be about 180. while on my back on exercise mat my Trainer observed sor of a v Shaped belly going up and down abdomen .
He suggestedbelly fat coming through a hernia.

It seems that it only noticeable when laying onthe floor. Otherwise looks like your normal beer belly fat belly that I am hoping to get rid of..
