I love being outside so much, I gave birth to both of my daughters in the great outdoors: Rumi in the peaceful garden of Ali's sister's house in the LA hills, and Indi on our Pennsylvania farm. Being among the birds and the flowers, and taking a slow hike, never fails to get my blood flowing. A few of my favorite ways to get active in nature? Outdoor yoga, canoeing, creek-wading, and walking. What's your fave way to get outside and break a sweat?
