What is “The Lagree Shake” And Why Do We Love It?
Why the Lagree Shake Means Your Workout Is Working
Shake Zone [SHāk-zōn]
The place where you go low, go slow, close your eyes, picture yourself
strangling your instructor (lovingly, of course), breathe deeply, and change your body.
If you’ve ever wondered why your muscles start trembling halfway through class, you’ve entered what we call The Lagree Shake Zone.
At Studio Physique in St. Petersburg, whether it’s your first class or your 500th, you’re almost guaranteed to feel it. Our instructors love the shake — in fact, we live for it! Why? Because it’s proof your body is working hard and your muscles are changing. The shake is one reason Lagree becomes addictive for so many people.
If you want to experience this in real time, you can explore our Lagree classes here.
What is the “Lagree Shake”?
In a feature by SELF Magazine, exercise physiologist Jacque Crockford explains:
“That shake isn’t a bad thing — it’s simply a sign that your body is becoming fatigued. Your muscle contractions are being interrupted because your nerves don’t have quite enough energy to keep firing perfectly.”
In other words, shaking = progress.
When you push through the shake (with good form, of course), you trigger small amounts of muscle breakdown — the foundation of strength-building. As those muscles rebuild, they become stronger, longer, and leaner.
According to experts at the Hospital for Special Surgery, when your muscles shake during a workout, it often signals fatigue of the neuromuscular system.
Most people are surprised the shake shows up so fast during class. The slow pace makes your muscles work harder than they’re used to, especially the small stabilizer muscles that support your joints. When these muscles stay active without a break, they start to tremble — not because you’re weak, but because they’re getting stronger.
The shake also helps you understand your body better. When you can feel your muscles working, it’s easier to stay focused on the move, your breath, and your form. This mind-muscle connection helps you move with more control and makes each rep more effective. Over time, you learn how to push yourself safely without overdoing it.
Many clients say the shake helps them see progress faster. The more you train your slow-twitch fibers, the longer you can hold positions, the steadier you become, and the stronger you feel during everyday movement. It’s one of the reasons Lagree changes your body so quickly — the shake shows the right muscles are firing.
So remember: the more you shake, the more you change.
Why Don’t I Get Shaky During Other Forms of Workouts?
You might wonder why this never happens during HIIT, spin, or traditional gym sessions. The reason is time under tension — the hallmark of Lagree Fitness.
During each exercise, your muscles are both stretching and contracting under resistance for an extended period — often one to two minutes per move. This constant effort causes your slow-twitch muscle fibers (Type 1) to fire continuously, leading to that delicious quiver. Slow-twitch muscle fibers (Type I) are built for endurance and longer contractions, unlike fast-twitch fibers, which fatigue quickly.
By contrast, workouts like running or cycling use fast-twitch (Type 2) fibers that fatigue quickly and recover just as fast.
At Studio Physique, our signature Lagree moves — planks, lunges, and slow-count extensions — keep your core and stabilizers activated the entire time, amplifying endurance, posture, and balance. You’re not just burning calories. You’re building body control.
How the Lagree Shake Improves Your Fitness
Activating your slow-twitch fibers consistently improves:
- Muscle endurance and stability
- Core strength and posture
- Joint support and flexibility
- Mind-muscle connection — better control in every workout
And because these muscles are engaged almost nonstop during class, your abs and glutes often feel the shake first.
You can build even more endurance by trying our Lagree + VersaClimber combo.
Embrace the Shake — Don’t Avoid It
Every SP member experiences the shake differently. New clients might feel it early and often, while advanced students chase that deeper, controlled burn.
Here’s how to find (and love) your shake zone:
- Go slower. Lagree rewards control, not speed.
- Get lower. That extra inch down makes all the difference.
- Focus. Visualize the muscle you’re working and squeeze it tight.
- Check your form. Good form = stronger shake.
- Adjust your springs. Add or remove resistance as cued by your trainer.
This is why Lagree challenges even the strongest men—it pushes muscles you don’t use in other workouts.
The goal isn’t to avoid shaking — it’s to embrace it. That’s where the magic happens.

FAQ
Can I stop shaking if it feels too intense?
Yes. You can always slow down, take a breath, or reset your form. The shake is normal, but you never have to push past what feels safe. As your core and stabilizer muscles get stronger, you’ll notice the shake feels more controlled. Our instructors help you adjust springs or modify moves so the shake feels challenging, not overwhelming.
