How to do: Bird Dog

1. Start on your hands and knees with a neutral spine and your abs pulled in.

2. Reach your opposite arm and leg out until they are parallel to the floor. Hold for six counts.

3. Come back to your hands and knees. If you're feeling tipsy, widen the stance you have on your hands and knees.

4. Then, continue alternating sides. Feeling flexible? Try to extend your raised leg a little higher each time.
