Why Your Joints Hurt Even Though You’re Strong: The Fascia & Mobility Connection

Strength Isn’t Always Enough

You train hard. You’ve built strength, you’re consistent, and you do the work. But then comes the frustration: sore knees after running, tight hips despite stretching, or a nagging shoulder that flares when you press overhead.

This is one of the most common stories we see at Underpin Health & Fitness—and it often comes down to fascia.

What Is Fascia? The “Hidden Web” of Your Body

Fascia is a continuous web of connective tissue that weaves throughout your entire body. It:

• Wraps around every muscle, tendon, ligament, nerve, and organ

• Provides structural support and transmits force during movement

• Stores and distributes tension like an elastic suit

• Is packed with nerve endings, making it highly sensitive

Think of fascia as the body’s internal wetsuit. If it’s hydrated and elastic, you move fluidly and without pain. If it’s dehydrated, restricted, or “glued down,” you’ll feel joint pain, stiffness, and restricted movement—even if your muscles are strong.

How Fascia Gets Stuck (and Why Joints Pay the Price)

• Dehydration: Fascia relies on water to stay slippery; dehydration turns it sticky.

• Repetitive Stress: Doing the same movement patterns (running, cycling, bench press) without variability causes fascia to thicken and restrict.

• Sedentary Behavior: Hours of sitting compress fascia, especially around the hips and spine.

• Overtraining or Poor Recovery: When your nervous system stays “on,” fascia contracts and loses elasticity.

• Nutrient Deficiency: Collagen and vitamin C are required for fascia repair—without them, tissues stiffen.

Result: Joints take the brunt of restricted fascia, leading to pain, inflammation, and wear.

How to Stimulate and Restore Fascia

1. Hydrate Your Fascia

Fascia acts like a sponge. It soaks up water when you move and compress it, and dries out when you’re sedentary.

• Drink half your bodyweight in ounces of water daily (add electrolytes for absorption).

• Add gentle bouncing drills (skipping, light pogo jumps) to “pump” fluid into fascia.

• Incorporate daily movement “snacks” (standing, twisting, walking) if you sit long hours.

2. Mobility Drills for Fascia Glide

Traditional stretching lengthens muscle, but fascia needs dynamic loading and multi-directional movement.

Daily Actionables (2–3 sets):

• 90/90 hip switches

• Cat-cow with side bends

• Lunge with rotation

• Ankle rockers

3. Myofascial Release (MFR)

Tools like foam rollers, massage guns, or lacrosse balls apply pressure to fascial restrictions.

How it works: Compression squeezes fluid out; release draws fresh fluid in.

• Roll 30–60 seconds per area, 2–3x per week.

• Focus: calves, quads, IT band edges, glutes, lats, pecs.

• Pair with mobility drills to “lock in” improvements.

4. Strength Training in All Planes

Most lifters overdo sagittal plane (forward/back) work. Fascia needs frontal (side-to-side) and transverse (rotational) loading too.

Actionables:

• Lateral lunges and Cossack squats

• Rotational lifts (cable chops, med ball throws)

• Tempo work (slow eccentrics, isometric holds)

5. Nutritional Support for Fascia

Fascia is collagen-rich and needs key nutrients for repair.

• Collagen or gelatin (10–20g daily)

• Vitamin C (200–500mg from citrus, berries, bell peppers)

• Protein (1.6–2.2g/kg of bodyweight)

• Omega-3s (salmon, sardines, or supplements)

 6. Train the Nervous System to Relax Fascia

Because fascia is richly innervated, your stress levels directly affect fascial tension.

Actionables:

• 5 minutes of box breathing daily (inhale 4, hold 4, exhale 4, hold 4)

• Yoga or flow-based stretching

• Evening walks in nature to downregulate stress

7. Elasticity Training (Rebound Loading)

Fascia loves spring-like, elastic movement.

2x per week:

• Skipping rope (3–5 minutes)

• Low pogo jumps (2–3 sets of 20)

• Light bounding drills for runners

Putting It All Together

If your joints ache despite your strength, the missing link isn’t more heavy lifting—it’s fascial health.

By hydrating fascia, restoring glide, training in multiple planes, fueling collagen, and calming your nervous system, you’ll unlock pain-free, fluid movement.

At Underpin Health & Fitness, our restorative approach means we don’t just make you stronger—we help you move better, recover faster, and feel pain-free by addressing the connective tissue most people overlook.

Key Takeaways

• Fascia is the hidden web that links strength to movement freedom.

• Hydration, mobility drills, myofascial release, and nutrient support restore fascia health.

• Training fascia means moving in all planes, not just up and down.

• Nervous system regulation is just as important as strength work for joint pain.
