Just in time for a whole new season of The Biggest Loser
, alumni Matt and Suzy Hoover delivered their second boy on Thursday, PEOPLE has learned exclusively.
Jax Paul, who was born at Valley Medical Hospital in Seattle, weighed in 7.6 lbs., and measured 18.75 inches long. He joins big brother Rex Timothy, 14 months. "We're so excited to add a new member to our family!" says Matt. "We're adding another healthy Hoover to our family and look forward to raising both boys in a healthy way with information we learned on the show."
As for the name Jax, Matt says, "Our first son is named Rex, and that was unique and we wanted something that sounded similar that was also unique."
Matt and Suzy, both 32, first met as competitors on the second season of The Biggest Loser
in 2005, which Hoover, a former wrestling coach, ended up winning. He then famously proposed to
second runner up Preston, a hairstylist, on the Today Show
in March 2006.
The couple got married
on Sept. 19, 2006 at a beachside wedding in Jamaica.
Now the Seattle-based pair have started a new company, BestLifeDesign.com
, a site that seeks to help people reach their health, fitness, financial, romantic and spiritual goals. In that vein, Hoover co-wrote the diet and fitness manual Matt Hoover's Guide to Life, Love and Losing Weight
with exercise physiologist Dr. Sheri Colberg, which hits bookstores nationwide on Sept. 23.
NBC's The Biggest Loser: Families
