Altar’d captures the journeys of engaged couples who are determined to lose weight and adopt healthy lifestyles before saying “I do.” Three months prior to their nuptials, the future bride and groom are paired with acclaimed fitness trainers Chris Marhefka and Erin Stutland to begin their transformations. However, in a twist that none of the participants see coming, the couples will be separated, unable to see each other for the entire 90 days until they are reunited for an incredible and emotional reveal at the altar.
