Exercises physical sits at the center of this dementia and brain health question.
Physical therapists consistently recommend seven core exercises to strengthen pelvic stability and support spinal alignment: glute bridges, dead bugs, bird dogs, clamshells, pelvic floor contractions, quadruped alternating limb raises, and modified planks. These exercises target the deep stabilizer muscles around your pelvis and lower spine that control posture, prevent falls, and reduce back pain—all particularly important for older adults and anyone managing cognitive decline, since balance and core strength directly influence fall risk. For people with dementia, maintaining pelvic and spinal stability helps preserve independence with walking, sitting, and transferring between chairs and beds.
This article walks through each exercise, explains why they matter, covers how to perform them safely, and addresses what to do if you’re starting with limited mobility or strength. The pelvic floor and deep core muscles act as an anchor for your entire spine. When these stabilizers weaken—whether from aging, inactivity, childbirth, or neurological changes—your spine loses support, leading to poor posture, chronic back pain, and increased fall risk. Physical therapists focus on these seven exercises because they’re effective, can be modified for different ability levels, and produce measurable improvements in stability and function within 4 to 6 weeks.

Why Pelvic Stability and Core Strength Matter for Spine Health
Your pelvic floor and deep core muscles form a muscular canister that stabilizes your spine from the inside. The pelvic floor sits at the base of this canister, the diaphragm forms the top, the transverse abdominis wraps around the sides, and the multifidus muscles run along the spine. When these muscles coordinate, they distribute forces evenly during movement, reducing strain on individual vertebrae and discs. Without this stability, your spine compensates by relying on ligaments and joint capsules, which can lead to inflammation, disc degeneration, and chronic pain.
For older adults—particularly those with cognitive changes—spinal stability also directly impacts balance and fall prevention. A strong core helps you catch yourself during a stumble, shift your weight smoothly when turning, and maintain upright posture while walking. Studies show that people with weak core stability fall more frequently and suffer more severe injuries from falls, making these exercises not just a wellness intervention but a safety measure. However, if someone already has spinal fusion surgery, severe osteoporosis with compression fractures, or acute spinal cord injury, some of these exercises may need modification or omission entirely—this is where working with a physical therapist becomes essential.
Foundation Exercises—Glute Bridges and Dead Bugs
The glute bridge is a foundation exercise because it activates your gluteus maximus, a large muscle that’s often underused in people who sit for long periods. To perform it, lie on your back with knees bent, feet flat on the floor about hip-width apart, and arms at your sides. Press through your heels to lift your hips until your body forms a straight line from knees to shoulders, hold for 2 to 3 seconds, then lower. Perform 2 sets of 12 to 15 repetitions. This exercise teaches your glutes to fire properly during standing and walking, which reduces the load on your lower back and stabilizes your pelvis during movement.
Dead bugs build coordination between your core and limbs while your spine remains in a neutral, protected position. Start by lying on your back with your arms extended straight up toward the ceiling and your knees bent at 90 degrees (shins parallel to the floor). Slowly extend your right leg, straightening it as you lower it toward the floor, while simultaneously lowering your left arm overhead, both hovering just above the floor without touching. Return to start and repeat on the opposite side. Perform 2 sets of 10 to 12 repetitions per side. The key limitation here is that dead bugs require cognitive coordination—if someone has significant cognitive decline, the movement pattern may be difficult to learn, and in that case, simpler exercises like glute bridges or supine marching are better starting points.
Progressive Strengthening—Bird Dogs and Modified Planks
The bird dog exercise targets your glutes, lower back stabilizers, and the connection between your upper and lower body. Begin on your hands and knees with your wrists under your shoulders and knees under your hips. Extend your right arm forward and your left leg backward simultaneously, creating a straight line from fingertips to heel, and hold for 2 to 3 seconds while engaging your core. Return to start and repeat on the opposite side. Perform 2 sets of 12 to 15 repetitions per side.
This exercise bridges the gap between isolated core work and functional movement, making it valuable for activities like reaching while standing or walking on uneven surfaces. Modified planks—performed on your knees rather than your toes—are an effective way to build endurance in your core without the intensity of a full plank. From your hands and knees, keep your body in a straight line from knees to shoulders and hold for 15 to 30 seconds, breathing steadily. Perform 3 to 4 repetitions, resting between them. A common misconception is that planks should be held until failure; in reality, planks done with proper form for shorter durations are far more effective than longer planks with sagging hips or held breath. If holding a plank on hands and knees is still too challenging, you can perform a plank against a wall or an incline (like a countertop), which reduces the load by 30 to 40 percent while maintaining the same muscle activation patterns.
Targeting the Pelvic Floor and Inner Thigh—Clamshells and Pelvic Floor Contractions
Clamshells strengthen your gluteus medius, a muscle on the outside of your hip that’s crucial for pelvic stability during single-leg activities like walking. Lie on your side with your hips and knees bent at 45 degrees and your feet together. Keeping your feet touching, open your top knee by rotating at the hip, lifting it toward the ceiling. You should feel tension on the outside of your top hip. Hold for 1 second, then close. Perform 2 to 3 sets of 15 to 20 repetitions per side.
The practical benefit is that stronger gluteus medius muscles help stabilize your pelvis when you stand on one leg to put on pants, step over obstacles, or walk on uneven ground. Pelvic floor contractions—often called Kegels—directly strengthen the muscles at the base of your pelvic canister. Sit or lie comfortably and imagine stopping the flow of urine mid-stream; the muscles you’d engage are your pelvic floor muscles. Contract them for a count of 3 seconds, then release for 3 seconds. Perform 2 to 3 sets of 10 contractions daily. A limitation of pelvic floor exercises is that many people, especially older adults and those with cognitive changes, find it difficult to isolate and feel these muscles, and over-gripping (contracting too hard) can actually increase tension and reduce function. If someone can’t perceive the contraction, working with a pelvic floor physical therapist who uses biofeedback devices can help confirm proper activation.
Building Coordination and Preventing Common Mistakes—Quadruped Alternating Limb Raises
Quadruped alternating limb raises combine the quadruped position (hands and knees) with lifting one arm or leg, creating an exercise that demands coordination, breathing, and whole-body stability. Start on your hands and knees. While engaging your core, raise your right arm straight in front of you to ear level while simultaneously raising your left leg straight behind you. Hold for 1 to 2 seconds, return to start, and repeat on the opposite side. Perform 2 sets of 10 to 12 repetitions per side.
This exercise is more complex than glute bridges or clamshells, so it’s best performed after you’ve built a foundation with simpler movements. A common mistake with most core exercises is holding your breath, which increases spinal pressure and reduces the stability benefit. Always breathe steadily—exhale during the effort phase (when you’re lifting or engaging) and inhale during the relaxation phase. Another warning: sharp, shooting pain during any of these exercises indicates a nerve issue and requires immediate medical evaluation. Dull muscle soreness is expected when starting a new exercise routine, but pain that radiates down a leg, causes numbness, or feels like a pinched nerve should prompt you to stop and consult your physical therapist.
Adapting Exercises for Limited Mobility and Dementia Care
If someone has very limited mobility, severe arthritis, or cognitive challenges, traditional exercise formats may not work. In these cases, modifications are essential: lying exercises like glute bridges and dead bugs require less balance than standing exercises and can be performed with caregiver assistance if needed.
Resistance can come from body weight alone or light ankle weights (1 to 3 pounds) added gradually over weeks. For individuals with dementia, repetitive, routine-based exercise works best—doing the same few exercises at the same time each day creates a familiar pattern that requires less decision-making and can be performed with minimal instruction or reminder. A 10-minute routine of glute bridges, supine marching (lying on your back and slowly lifting one knee at a time, as if marching), and simple pelvic floor contractions is often more sustainable and beneficial than a complex routine that’s forgotten or abandoned.
Building a Long-Term Routine and Maintaining Gains
Starting an exercise routine and maintaining it are two different challenges. For most people, consistency matters far more than intensity—performing these seven exercises 3 to 4 times per week for 6 months produces better results than intensive training once monthly. Research on older adults shows that gains in strength and balance can appear within 4 weeks, but those gains are lost within 3 to 4 weeks of stopping exercise.
This means that long-term spine health and fall prevention require ongoing commitment, not a one-time intervention. A practical approach is to integrate these exercises into an existing routine—perform them right after breakfast, after a daily walk, or in the evening before bed. Many people find that pairing exercise with another activity (television time, phone calls, or audiobooks) makes the routine more sustainable and less burdensome. Over time, as your stability improves, you can progress to more demanding variations, standing balance exercises, or functional movements that directly mimic daily activities you want to maintain.
Conclusion
The seven exercises recommended by physical therapists—glute bridges, dead bugs, bird dogs, clamshells, pelvic floor contractions, quadruped alternating limb raises, and modified planks—address the core stabilizers that support your spine, prevent falls, and reduce back pain. These exercises are effective because they target the deep muscles that work together to create spinal stability, and they can be modified to match almost any ability level, from someone recovering from surgery to someone with advanced dementia. Consistency, proper breathing, and attention to form matter far more than intensity, making these exercises accessible to most people.
If you’re starting an exercise routine, begin with the simplest versions (glute bridges and supine marching) and progress gradually over 2 to 3 weeks. If you have existing back pain, spinal surgery, neurological conditions, or other health concerns, work with a physical therapist to ensure exercises are appropriate for your situation and to correct form early, before bad habits develop. For older adults and those supporting someone with cognitive decline, these exercises are an investment in mobility, independence, and safety that pays dividends across all aspects of daily life.
Frequently Asked Questions
How long before I notice improvements in balance and pain?
Most people notice improved standing balance and reduced back pain within 3 to 4 weeks of consistent exercise, though strength gains continue for 8 to 12 weeks. Cognitive and neurological changes may progress more slowly, but regular exercise supports overall brain health and functional independence.
Can I do these exercises every day, or should I rest?
For foundational exercises like glute bridges and clamshells, daily performance is safe and often beneficial. More intense exercises like planks can be done 3 to 5 times per week with rest days in between. Listen to your body—persistent soreness suggests you need a day off, while mild muscle fatigue is normal and expected.
What if I have arthritis or joint pain—are these exercises safe?
Most of these exercises avoid high-impact movement and can be modified to work around painful joints. However, exercises performed lying down (glute bridges, dead bugs) are generally safer for people with joint pain than standing exercises. Consult your physical therapist or doctor to determine which movements are appropriate for your specific joints and condition.
Do I need equipment or a gym membership?
No—all seven exercises use body weight and can be performed at home. Light ankle weights (1 to 3 pounds) can add resistance as you progress, but they’re optional. A yoga mat or cushion makes floor exercises more comfortable but isn’t required.
How do I know if I’m doing the exercise correctly?
Proper form is confirmed by feeling muscle activation (mild fatigue or burn) in the intended muscles, steady breathing, and controlled movement without jerking or bouncing. If you’re unsure, a physical therapist can observe you, correct form, and provide feedback. Video tutorials from reputable sources (like physical therapy organizations or university health centers) can also guide you.
What’s the difference between pelvic floor exercises and core exercises?
Pelvic floor exercises target only the muscles at the base of your pelvis, while core exercises engage multiple muscles (glutes, abdominals, back stabilizers) that work together. Both are important—pelvic floor strength contributes to overall spinal stability and urinary health, while broader core exercises improve posture and prevent falls.
