Fred Winter does 100 push-ups a day – one for each year he has been alive.
But 30 years ago, the former teacher and U.S. Navy veteran (who was aboard a ship at the Battle of Okinawa during World War II) wasn’t in the best shape. When he turned 70, he decided that he should check in with other men his age.
“I wanted to see how I stacked up,” Winter, from Holland Michigan, tells PEOPLE. “And let’s just say, it wasn’t good.”
It was then that he got involved in the Senior Olympics.
