So I'm going to demonstrate how to do a bird dog for you. So you're going to start out in a quadruped position, which is basically what you see here. Your hands are under your shoulders and your knees are under your hips. So you're going to take one leg out high behind you.
You're going to point your toe. You're going to reach your opposite arm out in front of you, and you're going to reach. You have a couple options here. You could stay here if this is challenging enough. If you want more of a challenge, you're going to take your elbow into your knee and extend it long.
Extend it long. So I like to go about 5 to 15 reps on each side. So you're going to take your opposite leg and extend it high behind you, point your toe, reach out forward with your opposite arm, and take it in toward your belly button and extend. It's a great exercise for your abs and also a great tool to use as a warm up. And that's how you do a bird dog.
