I honestly don't see how working out in front of your parents is embarrassing unless your dad benches like 500 and you bench 20 and he sits there and laughs at you and calls you a weak friend as you're doing it. I remember in weight lifting in high school there was a kid that was 65 lbs. literally that was his weight and he couldn't even bench the bar people were so mean to him ): I hope he turned into a murderer and killed everyone who picked on him.
