Core and lower back

6 Bird Dog variations, from gentlest to strongest

Also called bird dog exercise, quadruped opposite arm leg, bird-dog.

Extending an opposite arm and leg from hands and knees while the spine stays still. It is the clearest trunk-control drill in the library, and the versions differ in how much limb is moving.

Start here

The list runs from the most supported version to the most demanding. Bird-Dog: Small Range is the one to begin with. Begin with the small-range version, or lift one limb at a time. Reaching further does not make this more effective: keeping your back still while you reach is what makes it work.
