Personal trainer Jillian Michaels seems to be adjusting to motherhood quite easily. We spotted the former "Biggest Loser" trainer and her partner Heidi Rhoades in Malibu, Calif., over the weekend with their two new additions to their family.

The couple pushed their kids in a stroller, and Jillian played with her daughter on the swings at a park.

Jillian and Heid's family grew quickly. Heidi gave birth to son Phoenix on May 3, and the couple welcomed 2-year-old daughter Lukensia from Haiti two weeks later.
