Keep your neck neutral. Look down, not forward.
Keep your supporting hand directly under your shoulder.
Among the target muscles, the erector spinae are exercised dynamically (i.e. they contract and change shape), whereas the obliques and rectus abdominis are exercised isometrically (they contract but do not change shape).
The high bird dog plank is an excellent whole-body functional exercise for strengthening your core and improving your balance and coordination.
Instead of alternating the limbs that you raise off the floor throughout the set, you can hold one arm and leg off the floor for one set and then hold the opposite arm and leg off the floor for another set. In this instance, all muscles will be exercised mainly isometrically.
The “high” in the name high bird dog plank refers to the fact that your weight is supported on your hand instead of on your elbow.
