K9 FITNESS — DAY 4: Protect the Spine
Meet the Multifidus
Small muscles can contribute to an important job. Today’s lesson looks at the multifidus, a group of muscles close to the spine, and uses familiar low-load movements to practice a steady trunk. The title is a training intention, not a promise that any exercise can prevent injury.
You cannot reliably judge one deep spinal muscle by whether you feel a burn. Think instead about the movement you can observe: a level pelvis, an unhurried reach, and a comfortable breathing rhythm. This session develops those habits through short repetitions rather than demanding long holds.
Today’s practice
Begin with 2–3 minutes of easy movement. Use the lowest suggested dose, keep effort comfortable, and rest between lessons whenever needed.
Bird dog — 6 per side. Start on hands and knees. Slide one foot back first, then add the opposite arm only when the pelvis stays level.
Dead bug heel slide — 6 per side. Lie with feet down and slide one heel away; bring it back before the trunk position changes.
Glute bridge — 8 repetitions. Lift through the hips, pause briefly, then lower without dropping.
Counter plank — 15 seconds. Lean onto a sturdy counter with straight body alignment. Step closer to make it easier.
Standing hip hinge — 6 repetitions. With soft knees, move hips backward toward a wall behind you. Keep the range small and stand tall again.
Choose one or two rounds at easy effort. If kneeling bothers your knees, add padding or use standing movements. Persistent back pain deserves an individual assessment; this lesson is general exercise education.
Canine partner routine
Enjoy a short sniff walk on even ground. At home, reward your dog for relaxing on a separate mat while you complete your movements. Calm participation counts.
Match activity to your dog’s age, health and conditioning. Avoid hot conditions and hot pavement; stop for unusual fatigue or distress. Ask your vet about activity limits when needed.
Make it useful tomorrow
Which cue helped more: reaching farther or moving more slowly? Keep the cue that improved control without increasing discomfort.
Keep a simple record: movement version, repetitions, effort and next-day response. You do not need a dog or equipment to belong in this course.
Before you train
This is general fitness education, not individualized rehabilitation. Choose pain-free movements; stop for sharp pain, dizziness, chest pain or unusual shortness of breath. If an injury or medical condition affects exercise, use advice from your clinician. Take recovery days between demanding sessions.
