"I love hiking with girlfriends," says the incredibly fit actress, who also works out with celeb trainer Valerie Waters and does Body By Simone dance cardio classes. "It is a no-brainer, great way to spend a couple of hours, for sure. And in Los Angeles, it's always been one of my go-to workouts. And there's so many great hikes all over LA. I feel really lucky to live there and be able to take advantage of them."
As for cooling off in the water, Jennifer's excited to hit the pool with her family in the coming months. "I think that my littlest one will finally be water safe—with supervision, obviously—this summer, and so I'm excited to all be swimming together without a baby holding onto me because that's always a big moment."
Jennifer points out that, "whenever you're in the water, you have to be super careful because the water magnifies the effects of the sun." And she says she and her friends lay on the sunscreen during their hikes, too: "You would be amazed—just as we're walking out the door, we all pass it around and get another dose."
