Leg day. Heavy Romanian deadlifts.
The weight flies up and down, smooth as butter. Form is pristine.
But where are the hamstrings? The glutes? Nowhere.
If FitTok is right, this is a disaster.
Or maybe not.
There’s a whole philosophy out there called the mind-muscle connection. It’s the idea that you must feel the specific muscle firing before it actually does any work.
“The mind-muscle connection means focusing on the muscle you want to train instead of just moving the weight.”
Susie Reiner, PhD
Dr. Susie Reiner from Seton Hall University puts it bluntly. Don’t think about getting from point A to point B. Think about the muscle contracting. Shortening. Producing force.
The theory goes like this: if you focus harder, the muscle activates more. Better activation equals more growth.
Right?
Here’s the problem. Some muscles are stubborn. They refuse to announce their presence. The glutes, the lats, the hamstrings.
You lift, you grind, you sweat. But the signal is faint. Or absent.
Can you build muscle in the dark?
Feeling vs. Growth
Science says focusing works. But only sometimes.
A 2019 study looked at experienced lifters on bench presses. When told to focus specifically on their triceps? Tricep activation went up.
Especially with lighter weights.
Dr. Rachelle Reed notes this clearly. Focusing directs blood flow. It recruits fibers.
This touches on three main drivers of hypertrophy (muscle growth):
* Mechanical tension – pulling hard against a load
* Metabolic stress – the “burn”
* Muscle damage – microscopic tears from effort
Higher activation might boost these factors.
It might.
But it doesn’t dictate it.
Dr. Reiner points out that some muscles are just hard to sense due to anatomy. Complexity plays a role. Your experience level matters more than your ability to feel a twitch.
Just because you can’t feel it doesn’t mean it’s dead.
Muscles grow when they face stress over time. That’s the bottom line.
Load it heavy enough.
Keep increasing the load.
Eat enough protein.
Sleep.
That’s the checklist. The mind-muscle trick? It’s flavoring, not the main course.
“Muscles grow because they are exposed to sufficient training stimulus over time. The mind-muscle is just one piece.”
Dr. Susie Reiner
So if you’re strong, you’re probably fine.
If you want to dial it in? Fine. Use it. But don’t panic when you can’t find it.
How to find the feeling
If you are the type of person who needs that tactile feedback, stop trying so hard and start doing these things.
- Ditch the ego.
Put more weight down. If you’re relying on momentum, the target muscle is checking out. Proper form forces the right muscle to do the work. It’s called motor learning. Move with intent. Breathe. - Exhale when lifting (concentric)
- Inhale when lowering (eccentric)
Simple. Boring. Effective.
-
Go lighter.
Again. If the weight is too heavy, your nervous system recruits every helper muscle available. Your form suffers. Your focus blurs. Reduce the weight so the target muscle has to scream. -
Slow it down.
Don’t just jerk the bar up and let gravity bring it back down. Control the descent.
Lower it for three seconds. Four if you have to. Pause at the bottom.
Force yourself to recognize the contraction.
The real takeaway
Most people don’t strength train at all.
The WHO says do two sessions a week.
If you are doing those, you are already ahead.
Chasing a feeling might optimize the top 5% of your gains.
It won’t matter if you skip leg day because you couldn’t find your quads.
Consistency beats intention every time.
So keep lifting. Eat your chicken.
If you feel it? Great.
If not? The muscles don’t care.
