“The bird dog forces you to keep your core stiff,” says Jack. “Lifting your knees off the ground just a couple of inches—as you do in this exercise—makes it even more challenging to keep your torso still as you switch arms and legs.” That means your hips and lower-back muscles, obliques, rectus abdominis (also known as the six-pack muscles) are working together to keep your spine stable.
The Torso Track comes out as number 5 for effective ab exercises, but this is one of my least favorite exercises because it can cause lower-back pain, particularly if you roll out too far. In fact, in the ACE study, researchers found that a significant number of subjects reported lower-back pain, so you may want to skip the expense, and discomfort, of this one and choose other exercises that can target the abs with equal effectiveness.
