He asks his son what he wants to do first and initially suggests they work their legs. However, Micah insists that he always starts with chest exercises. He goes over to the bench press and invites Barry to be “my spotter.”

Micah does a rep, then huffs about how heavy the bar is. “Comedy routine in the midst of bench press,” Barry laughs as his son continues to push himself. Micah sets the bar down after a few reps and says it’s “just a warmup.”
