Ever wonder why you feel like a stiff board or in pain when you first wake up or sit too long?
It’s all thanks to a fascinating science concept called thixotropy, and it challenges everything we think we know about resting away our tightness.
When you feel stiff, your instinct might be to sit down, rest, and protect your body. But doing that actually locks the stiffness in.
Think of your body’s connective tissue, or fascia, like a jar of honey. When honey sits still in a cold cupboard, it gets thick, solid, and incredibly sticky. If you try to force a spoon through it, it resists.
If you look at the photo below, you can see why the fascia makes people stiff. It encapsulates the muscles and pulls when tight depending on the origins and insertion points of each muscle. Fascia doesn’t have a start or stopping point like your tendons and ligaments, if is an entire amazing network throughout your body. 
What happens to your muscles and joints when you stay seated or rest for too long? Your internal "honey" thickens up, gluing your tissues together and making movement feel like a chore or worse, can be quite painful but why?
This "honey-like" stickiness is also why resting too much can lead to direct pain.
So where does the pain come from?
Your fascia is actually packed with thousands of microscopic, highly sensitive nerve endings. When you stay still and let that tissue dry up, those sticky knots, called adhesions, physically clamp down and pinch your local nerves. It behaves just like a tight snag in a knitted sweater; a tight spot in one area pulls on the tissue further away, triggering deep aches and stiffness in places you least expect it.
But here’s the cool part: just like warming up that honey, your fascia completely changes consistency when you move.
This is why pain meds can cause some relief but aren’t doing anything for the fascia to actually go to the root of the problem which is your fascia and connective tissue being stiff.
When you move with fitness, your body temperature rises and mechanical stress acts like a blender on that internal stickiness.
In a matter of minutes, that thick, cold honey transforms into a fluid, slippery, and bouncy gel. Suddenly, your tissues slide easily, your joints unlock, and your body moves with total freedom.
What’s a Fast Way to Make this Happen?
Something as simple as a 30-minute spin class at Inner Fit Studios (shameless plug), results in two amazing things happen:
- Heat: Your body temperature rises, literally melting that internal stickiness.
- Mechanical Stress: The continuous, rhythmic pedalling acts like a blender, instantly turning that thick honey into a fluid, slippery gel.
In just 30 minutes, your tissues go from stiff and glued to loose, bouncy, and free.
Imagine how much better your body will feel, sleep, and function if you were exercised daily for a minimum of 30 minutes a day?
Remember, moving is good, but fitness where your heart rate is elevated and you are sweating is where the magic happens for your fascia.
Want the ultimate weapon against stiffness? Try our 20/20/20 class. By combining 20 minutes of spin, 20 minutes of strength, and 20 minutes of core, you target your fascia from every possible angle. The spin segment melts the fluid and gets it moving. Then, the strength and core work stretch and load those freshly hydrated tissues through different planes of motion, locking in full-body mobility that lasts all day. Same for a circuit type class.
HYROX athletes, take note: If you tackle our HYROX training on Mondays, jumping into a 30-minute spin class right before will do wonders for your performance. By pre-melting that stiffness and unlocking your fascial glide, your joints can move through a full range of motion. This increases your power output and drastically reduces your risk of injury during those heavy sled pushes and wall balls. This is why you see pro athletes like hockey and football players always on bikes before and after games or practice.
But the real hard part is shifting our mindset away from thinking that resting or meds only cures stiffness.
👉Rest makes you thick and sticky.
👉 Movement makes you fluid and free. Keep your body warm, keep your tissues moving, and don't let the stillness glue you down.
And for my office workers, this is why it is important to get up and move every 20-30 minutes. Something as simple as 10 chair squats every 30 minutes or a 5 minute walk around the office or up and down and flight of stairs will keep you fluid and less stiff. Or make sure to pack your bags and get a workout in before or after work because a lifetime of office work is now showing how dangerous sitting is for our bodies and backed up by study after study.
So if you “don’t feel like exercising” or are tired or sore, remember it is the actual workout that will make you feel better, not laying on a couch.
Happy Training!
