Red Flags: When to Stop and Seek Medical Care

Most back pain is manageable with the right approach. But there are specific symptoms that require immediate medical attention. These are non-negotiable. If you experience any of the following, see a doctor:

• New bladder or bowel problems (difficulty controlling either) • Numbness around the saddle/groin area • Rapidly worsening leg weakness • Unexplained fever, chills, or weight loss • Severe pain after a significant trauma • Feeling physically unsafe

These are rare, but they're serious. Everything else in this program assumes that red flags are not present. If any of these show up at any point, pause the program and get in-person care.

Every session has a “Does this hurt?” button. Tap it if something doesn’t feel right.

Walking: 30 min

Stand / walk / change posture every 20 to 40 min through the day

Also walk on rest days at the same duration

Today’s exercises

Some soreness during exercise is normal. Sharp, escalating pain is not.

  1. Seated good morning

    Exercise 1

    Seated good morning

    3 × 15+

    Hands behind head: CAP for this program (no added load); FLAT-BACK neutral hinge

    How to do it
    1. 1Sit tall on a flat bench or the edge of a firm chair with your feet wide apart and knees bent so that your heels are roughly beneath your knees.
    2. 2Breathe in and brace your core.
    3. 3Hinge forward slowly while maintaining your brace and a neutral spine.
    4. 4Fight to keep a straight back and stop the movement when you feel that your back may begin to round.
    5. 5Drive down through your feet and push your hips forward into the bench to return to the starting position.

    Why this exercise

    A seated position increases stability and lets you build confidence with hinging at the hips before you try it standing. The extra stability means 100% of your attention can go to moving through the hips with a locked, neutral spine.

    Make it easier

    • Micro-hinge: lean only as far as stays comfortable, build over time
    • Rest your hands on your thighs to support your torso
    • Drop down a rung of the lever ladder

    Make it harder

    • Climb the lever ladder (longer lever = harder): (1) hands on thighs
    • Arms crossed on your chest
    • Hands behind your head (do not push your chin down)
    • Hug a weighted object to your chest (a book, water jug, or filled bag)
    • Increase the depth of the hinge (back must not round into flexion)
  2. Single-leg RDL / hip hinge

    Exercise 2

    Single-leg RDL / hip hinge

    2-3 × 8/side

    Fingertip support

    How to do it
    1. 1Position yourself near a supporting surface for your hand.
    2. 2Stand tall on one leg with that knee slightly unlocked (not rigid) and gently brace your core.
    3. 3Tip your chest forward while moving the raised leg straight out behind you.
    4. 4Stop when torso and trailing leg are roughly parallel to the floor, or sooner if balance shifts or your back begins to round into flexion.
    5. 5Squeeze the standing-leg glute and pull your hips forward to return to standing.

    Why this exercise

    This is a step up from the standing hip hinge. Standing on one leg asks far more of the glutes, hamstrings, and the small stabilising hip muscles, while still teaching your back to stay neutral.

    Make it easier

    • Drop back to the standing hip hinge and build strength there
    • Let the trailing toes lightly brush the floor for balance
    • Press more firmly into the supporting surface

    Make it harder

    • Reduce support: full hand support
    • Fingertips only
    • Light or no support
    • Hold a light weight in the hand opposite your standing leg
  3. Bodyweight hip hinge (hands on thighs)

    Exercise 3

    Bodyweight hip hinge (hands on thighs)

    2 × 12

    Warm-up

    How to do it
    1. 1Stand with your feet about hip-width apart and knees slightly bent.
    2. 2Place your hands lightly on the tops of your thighs and gently brace your core.
    3. 3Push your hips back behind you slowly and slide your hands down your thighs for support. Imagine you are closing a car door with your butt, letting your chest tip forward while keeping your back straight.
    4. 4Stop when you feel a stretch in your hamstrings or if you notice your back beginning to round, then return to standing by driving your hips forward and straightening your legs.

    Why this exercise

    This is a skill drill, not a workout. It teaches you how to bend using hips and legs while keeping your trunk stable - basically the foundation for picking things up without relying on rounding your spine into flexion.

    Make it easier

    • Smaller hinge (hands don't slide far)
    • Practice against a wall (hips tap wall)

    Make it harder

    • Deeper hinge while staying neutral (spine)
    • Remove hand support gradually
    • Hold a light object, once the pattern is automatic
  4. Single-leg glute bridge

    Exercise 4

    Single-leg glute bridge

    2 × 8/side × 3s pause at top
    How to do it
    1. 1Lie on your back with both knees bent and feet flat on the floor, about hip-width apart.
    2. 2Lift one foot off the floor and hold that knee bent toward your chest, or keep the leg straight out, whichever you prefer.
    3. 3Gently brace your core, squeeze the glute of your planted leg, and push through that heel to lift your hips until your body forms a straight line from shoulders to knee.
    4. 4Keep your hips level (do not let one side dip or rotate), pause briefly, then lower with control and repeat for the prescribed reps before switching legs.

    Why this exercise

    Strong glutes drive your hips so your lower back doesn't have to, which is one of the best ways to take load off a sore spine. Lifting one foot roughly doubles the demand on the working hip compared with the two-leg bridge, so it's a big step up in glute strength with no extra kit.

    Make it easier

    • Drop back to the double-leg glute bridge
    • Lifted-leg toe lightly touches the floor
    • No pause, fewer reps

    Make it harder

    • Add a 2-3 second pause at the top
    • Hip thrust
    • Single-leg hip thrust
    • Rest a weight on your hips
  5. Step-ups

    Exercise 5

    Step-ups

    2 × 8/side, higher step
    How to do it
    1. 1Stand facing a stable low step or platform with your feet about hip-width apart.
    2. 2Place one foot firmly on the raised surface, lean your body slightly forward over that leg, and gently brace your core.
    3. 3Push through the heel of the front foot to straighten that leg and bring your body up onto the step.
    4. 4Slowly lower back down with control, lightly tapping the other foot to the floor before repeating for the prescribed repetitions on each leg.
    5. 5Stairs are a great location for this as they often have railings for additional balance support.

    Why this exercise

    Step-ups are simple, functional leg strength with built-in balance work. Great for building walking/stairs capacity and easing back into 'real life strength' without needing a gym setup.

    Make it easier

    • Lower step
    • Hold a railing or fingertip support
    • Reduce reps and go slower

    Make it harder

    • Higher step/platform
    • Add load by holding a weight in one hand
    • Slow eccentric (3-4 seconds down) if your next-day response behaves
  6. Side Plank (from feet)

    Exercise 6

    Side Plank (from feet)

    2 × 15-20s/side
    How to do it
    1. 1Lie on your side with your legs straight, elbow under your shoulder, and body in a straight line from elbow to shoulders.
    2. 2Lightly brace, then lift your hips so your body forms a straight line; hold for the prescribed time, breathing steadily, then lower with control and repeat on both sides.

    Why this exercise

    Same idea as the knees version, just more difficult due to the longer lever from being on your feet instead of your knees! This is the middle rung of the side-plank ladder.

    Make it easier

    • Back to knees version
    • Stagger feet for a wider base
    • Shorter holds with perfect alignment

    Make it harder

    • Longer holds
    • Lift your top leg a few inches and hold it (abduction) while you brace
    • Add resistance (a weight or object) onto your side while you hold
  7. Bird Dog

    Exercise 7

    Bird Dog

    2 × 5/side × 5-8+s hold
    How to do it
    1. 1Start on hands and knees with your knees directly below your hips and hands below shoulders.
    2. 2Breathe in and brace your core, then slowly extend one arm forward and the opposite leg back without letting your low back sag or twist (the raised arm and leg should be parallel with the floor). Hold for the prescribed time in the extended position, then return and switch sides.

    Why this exercise

    Life is basically 'keep your trunk stable while a limb does something.' Bird dogs trains that skill. Another favourite of Dr. Stuart McGill's and the final exercise of his 'big 3'.

    Make it easier

    • Arm-only reach
    • Leg-only reach (toe slide back)
    • Shorter holds

    Make it harder

    • Longer holds and more repetitions
    • Slower tempo (3-5 seconds out, 3-5 back)
    • Increase the width of your hands and knees on the floor (the width of your base)
  8. Front plank

    Exercise 8

    Front plank

    2 × 25-30s
    How to do it
    1. 1Set up face down with your forearms on the floor, elbows directly under your shoulders, and your feet (or knees) behind you.
    2. 2Take a breath in and brace your core hard, then lift your hips so your body forms one straight line from your head to your heels (or knees).
    3. 3Squeeze your glutes and gently tuck your tailbone so your low back does not sag toward the floor.
    4. 4Hold for the prescribed time, breathing steadily, then lower with control and rest.

    Why this exercise

    A braced, stable trunk lets your spine stay still and protected while your arms and legs do the work, which is exactly what spares your back during everyday lifting and carrying. The plank is the step up from the curl-up: instead of a small lift you hold a full-body brace against gravity, so it builds far more whole-body core endurance.

    Make it easier

    • Plank from your knees
    • Hands on a raised surface (a couch or bench)
    • Shorter holds

    Make it harder

    • Knees, then full plank on your feet
    • Long-lever plank (walk your elbows further forward)
    • Feet-elevated plank (toes up on a step)
    • Longer holds
  9. Chin tucks (sitting or standing)

    Exercise 9

    Chin tucks (sitting or standing)

    2 × 8 reps, 8s hold
    How to do it
    1. 1Sit or stand tall with your shoulders relaxed and your eyes looking straight ahead.
    2. 2Gently draw your chin straight back as if making a "double chin," keeping your head level (do not tilt up or down).
    3. 3You should feel a mild stretch or activation at the base of your skull and the front of your neck, not pain.
    4. 4Hold briefly for the prescribed time, then relax and repeat for the recommended repetitions.

    Why this exercise

    Modern life is basically a chin-forward endurance sport. We are sitting at desks, staring at screens...then we go home and stare at more screens while slouching on the couch. Chin tucks help retrain neck flexors while stretching the posterior extensors. This helps correct a forward neck posture that most of us are guilty of. Get ready to show your double chin.

    Make it easier

    • Smaller movement (gentle glide back)
    • Shorter holds
    • Do it lying down (often easier to feel correctly)

    Make it harder

    • Longer holds / more reps
    • Add it into posture breaks (set-based habit)
  10. Shoulder-blade squeezes

    Exercise 10

    Shoulder-blade squeezes

    2 × 8 reps, 8-10s hold
    How to do it
    1. 1Sit or stand tall with your shoulders relaxed. Raise your arms out in front of you.
    2. 2Pull your elbows and arms straight back and imagine trying to touch your elbows together behind your back.
    3. 3If you have access to a gym, or weights, rowing movements or reverse pec-decks are what we're aiming for.
    4. 4Pause briefly at the end position, squeezing and feeling the muscles between your shoulder blades work, then return slowly and repeat for the prescribed repetitions.

    Why this exercise

    When upper back/neck symptoms are part of the picture, restoring scapular control is often a big win. This builds endurance in the "posture muscles" and helps make us aware of what muscles should activate to correct our posture.

  11. Gentle thoracic rotations (open-book)

    Exercise 11

    Gentle thoracic rotations (open-book)

    1 × 8/side
    How to do it
    1. 1Start lying on your side with knees bent to 90 degrees and your arms stretched out straight at 90 degrees(open-book position).
    2. 2Slowly rotate your upper body to open your chest, letting your top arm move away from the other than remains on the supporting surface.
    3. 3Move only into a comfortable range, pause briefly, then return to the starting position and repeat for the prescribed repetitions on each side.

    Why this exercise

    A stiff mid-back often forces your low back or neck to move more than they'd like. Open-book helps restore rotation where it's supposed to come from (thoracic spine) in a controlled, comfortable way. Perform this slowly and under control.

  12. Standing arm sweeps

    Exercise 12

    Standing arm sweeps

    1 × 10 reps
    How to do it
    1. 1Stand tall with your feet about hip-width apart and your shoulders relaxed.
    2. 2Bring your hands together behind your back or clasp them lightly if your shoulders allow.
    3. 3With straight arms, sweep them out to the sides and then up overhead in a smooth arc while keeping your trunk still and stable.
    4. 4Lower your arms back down in front of you or to your sides and repeat for the prescribed repetitions, keeping the movement comfortable and controlled.

    Why this exercise

    A simple way to open up shoulder motion and wake up the upper back without twisting or bending the trunk. Do your best to not sway or bend your arms. It is okay if your shoulders are a little cranky doing this, they'll warm up to it after a few movements.
