The Biggest Loser's Marty and Amy Gain a Baby!
Marty Wolff and his wife Amy, who met during the third season of NBC's The Biggest Loser in 2007 and got married in March 2008, have marked another milestone – welcoming their first child.

Amy, 30, delivered a baby boy at Alegent Lakeside Hospital in Omaha, Neb., on the morning of the Fourth of July, PEOPLE has learned exclusively. At Blaine Patrick Wolff's first weigh-in, he measured a healthy 10 lbs., 14 oz., and was 22 ½ inches long.

"We are all doing great," Amy says, "and are enjoying getting to know each other."

Amy and husband Marty, 28, who live in Omaha, run a weight loss and self-improvement program called Reality Wellness. "We made a decision to stay in fitness to keep ourselves accountable," Amy told PEOPLE in December. "We are still comfortable where we are."
