Leaving her little ladies at home, Heidi Klum and Martin Kristen took her sons for a hike on Sunday (May 19) in Los Angeles.

Donning a New Balance tee and black capri leggings, the mother-of-four did some stretching with her bodyguard boyfriend and boys Henry and Samuel before setting off.

With the German-born supermodel leading the way, the foursome made it to the top of the Baldwin Hills, where they took in the view of downtown L.A.

Back on flat land, the group met up with Klum’s daughter Lou and headed to Starbucks for some cold beverages after the warm trek.

In career news, the “Project Runway” host will soon be seen as a new judge on season eight of “America’s Got Talent,” when it returns on June 4.
