Bird dog: how to do it
In short
A slow move on hands and knees where you reach one arm and the opposite leg out and keep your trunk still. Works: core, lower back and balance.

How to do it
- Get down onto a mat or folded towel on a non-slip floor, on your hands and knees. Hands under shoulders, knees under hips.
- Keep your back in a long, neutral line and your neck relaxed, eyes on the floor.
- Slide your right leg straight back, toes on the floor. Then reach your left arm forward.
- Lift both only to the height of your back, not higher. Pause for a breath.
- Bring them back slowly and switch to the left leg and right arm.
- Do 4 slow reps, alternating sides.
As you go
- Keep your hips level, as if a cup of water sat on your lower back.
- Breathe out as you reach, breathe in as you return.
- Reach long instead of lifting high.

An easier and a harder version
Easier
Reach only an arm, or only a leg, at a time. Slide the foot along the floor.
Harder
Pause for 3 seconds at the top, or bring your elbow and knee together under your body before you reach out again.
Take care
- Wrists: if your wrists complain, make soft fists or rest on your forearms.
- Knees: put a folded towel under your knees if the floor is hard.
- Back: if your lower back aches, make the reach smaller and keep your leg lower.
- Balance: widen your knees a little to feel steadier.
