FITNESS & WELLNESS
I couldn't work out for a long stretch recently. But I could still lesson plan. So I dove into the research — and what I found genuinely surprised me.
Here's something I had read about previously, but didn't fully appreciate until life forced me to slow down: your brain doesn't always need your body to train your body.
I know; it is a lot to take in. Stay with me…
When I was sidelined by some health issues, I was, to be honest, frustrated. Teaching fitness is what I do — it's how I show up in the world, and losing that routine rattled me. I'll be straight with you: visualizing workouts did not fix my mood. Getting back on Zoom with my people did. Researching, designing new programs, and having something to build toward — that's what kept me going.
But the research I fell into during that time? It genuinely blew me away. Because it turns out that the line between "thinking about exercise" and "doing exercise" is blurrier than any of us learned in gym class.
The Science of Imagining Movement
In sports psychology and neuroscience, it's called motor imagery — mentally simulating a physical movement without actually performing it. Athletes have used it for decades. But the research has started showing something remarkable: for regular people, especially those recovering from injury or illness, it can actually build and preserve strength.
RESEARCH SPOTLIGHT — CLEVELAND CLINIC / NEUROPSYCHOLOGIA, 2004
Researchers led by Dr. Guang Yue at the Cleveland Clinic divided participants into groups: one physically exercised their finger muscles, one did nothing, and one only imagined exercising. After 12 weeks, the mental imagery group increased their strength by a meaningful margin — without moving a muscle. The researchers attributed this to enhanced brain-to-muscle communication, not muscle growth itself.
The takeaway: your brain was practicing the whole time.
35% Strength increase reported in some mental imagery studies — with no physical movement
24% Physical strength increase through mental practice alone in one kinesthetic imagery trial
50% Reduction in strength loss during immobilization when mental imagery was practiced (Clark et al.)
A 2013 study published in Frontiers in Human Neuroscience (Yao, Ranganathan, et al.) compared two types of imagery: internal (feeling the movement from inside your body) and external (watching yourself from the outside). The internal group — the ones who imagined what the contraction actually felt like — showed a 10.8% strength gain. The external imagery group showed no significant change.
This distinction matters a lot for how we use this practically.
Internal vs. External: Which Kind of "Imagining" Actually Works?
Think of external imagery as watching a movie of yourself doing a squat. You can see your form, your posture, your body in motion. It's useful for learning new movements and building confidence — especially if you're newer to exercise.
Internal imagery is different. You close your eyes and feel your feet planted on the floor, feel the tension building in your quads as you lower, feel the muscles engage as you drive back up. Your heart rate might tick up slightly. Your body is responding as if something is actually happening.
"Internal imagery generates significantly more physiological responses — including changes in heart rate, blood pressure, and respiration — compared to external imagery." — Research summary, Dr. Sarah McKay, neuroscientist
A systematic review in the Journal of Strength and Conditioning Research (Lebon, Collet, Guillot, 2010) confirmed that mental imagery training can improve strength, and that the gains are highest — 10–30% over 4–6 weeks — when people practice 3 to 5 times per week and use that kinesthetic, first-person, felt-from-the-inside approach.
What's happening neurologically is that the brain is literally reinforcing the motor pathways — the communication highways between your brain and your muscles — even without sending a signal all the way to your body. Think of it as keeping the road well-maintained even when no cars are driving on it.
WHAT CHANGES IN THE BRAIN
Motor imagery activates the same cortical areas as physical movement: the primary motor cortex, premotor cortex, and supplementary motor area. EEG studies show increased brain signal in these regions during imagery training. Even spinal cord excitability increases — sometimes after just a single session.
When you return to physical training, those pathways are primed. Motor unit recruitment improves. Voluntary activation improves. The body is ready to do what the brain has been rehearsing.
What This Means When You're Sidelined
Whether it's surgery, illness, injury, or just a season of life where getting to a class isn't possible — mental imagery is a legitimate tool in your fitness toolkit. It won't replace physical training. It won't build muscle mass the way squats do. But it can:
→ Slow down the strength you lose during a forced break
→ Reinforce the neural pathways for movements you've been practicing
→ Keep your brain "in shape" for the movements you'll return to
→ Help you come back faster and with better motor control
And when combined with real training? The research is even more encouraging. Studies show that athletes who combined mental imagery with physical training increased their one-rep max by up to 27%, compared to about 15–16% for physical training alone.
How to Actually Do It
This isn't just "picture yourself at the gym." Here's how to make it work:
Get still and quiet first
Find a comfortable seated or lying position. Close your eyes. Take a few slow breaths and let your body settle. This isn't meditation — but it borrows that settling quality.
Choose a specific movement you know well
A squat, a bicep curl, a shoulder press from Strength in Motion. The more familiar the movement, the richer your imagery will be. Vague visualization produces vague results.
Go internal — feel it, don't watch it
Don't picture yourself from across the room. Instead, feel the weight in your hand, feel your feet ground into the floor, feel the muscles engage. Match the real timing and effort of the movement.
Keep the same duration and intensity
If a set takes 30 seconds in real life, take 30 seconds mentally. Don't rush it. The brain is learning the same way it does when you're actually moving.
Practice consistently — 3 to 5 times a week
Like physical training, the gains come from regularity. Even 10–15 minutes a session adds up.
An Honest Note From Me
I want to be real with you, because that's how we do things around here.
When I was going through my health stuff, mental imagery was intellectually fascinating. I spent hours in the research. I designed entire new programs for my classes, including Strength in Motion, during that time. Having a project — having something to build toward and people to build it for — was what actually lifted my spirits.
The imagery exercises? They kept my mind sharp and connected to movement. But they didn't fix the harder emotional parts of being unwell and out of my routine. I want you to know that, because I think sometimes wellness culture oversells the power of any one thing. Mental imagery is a real, research-backed tool. It is not a replacement for community, purpose, or getting back to doing the things you love with people you enjoy.
Which is exactly why, when I came back, I came back with new programs and even more intention. Because the best thing that kept me going wasn't imagining exercise — it was knowing I had people waiting for me on the other side of that Zoom screen.
