The Science Behind Functional Movements Performed at High Intensity

I know, I know, "But Dale you said the most effective workout is the one I would do!" 

THAT STILL STANDS TRUE. Because doing something is more important than doing NOTHING.

BUT the science speaks for itself when it comes to actual results.

When it comes to fitness, not all workouts are created equal. Some programs isolate muscles, some focus only on endurance, and others aim for flexibility. But if your goal is overall strength, fitness, and resilience that actually carries over into your daily life, there's one approach that consistently delivers results: functional movements performed at relatively high intensity.

At Vital, this philosophy shapes much of our training. Here's why the science supports it.

What Are Functional Movements?

Functional movements are exercises that mimic how your body naturally moves in everyday life. Squats, deadlifts, presses, pushes, pulls, and carries are all considered functional because they recruit multiple joints and muscle groups at once.

Unlike machine-based exercises that isolate a single muscle, functional movements train your body as a system. Think about it: when you pick up a heavy box or climb a flight of stairs, you're not just using your legs, you're engaging your core, back, and stabilizers too.

Science says: Multi-joint, compound movements lead to greater improvements in strength, balance, and mobility than isolated exercises because they activate more muscle fibers and demand greater coordination.

Why Intensity Matters

High intensity doesn't mean reckless or unsafe, it means working hard relative to your ability. For one person, that may mean sprinting. For another, it could be moving quickly with light weights.

Intensity is important because it creates the stress your body needs to adapt. According to the SAID Principle (Specific Adaptation to Imposed Demands), your body improves in response to the challenges you place on it. Push a little harder, and your muscles, heart, and lungs adapt to handle more next time.

Science says: Research consistently shows that higher-intensity training (when properly scaled) leads to faster improvements in strength, endurance, fat loss, and overall fitness compared to low-intensity exercise.

The Benefits of Functional Movements at High Intensity

1. Efficiency
   Because these movements engage multiple muscles, you burn more calories and build more strength in less time.

2. Transferability
   The strength and coordination you build in the gym translates to everyday life, whether that's carrying groceries, moving furniture, or chasing your kids.

3. Broad Fitness Development
   Functional high-intensity training builds not just strength or cardio in isolation, but a well-rounded fitness: power, endurance, balance, coordination, and resilience.

4. Scalability
   Every movement and intensity can be adjusted. A new member may start with bodyweight squats, while an experienced athlete may squat with heavy weight. Both are working at their own relative high intensity, and both benefit.

Why This Matters for You

Most people don't just want to look fit, they want to feel fit. They want to be strong, capable, and confident in how they move through life. Functional movements performed at relative high intensity give you exactly that.

They prepare you not just for the next workout, but for the challenges of daily life. They make you stronger, healthier, and more resilient, inside and outside the gym.

Final Thought

The science is clear: functional movements performed at relatively high intensity are one of the most effective ways to train. They're efficient, adaptable, and build real-world strength and conditioning.

If you've been stuck in routines that feel like they aren't moving the needle, it may be time to challenge yourself with training that's designed for how your body was meant to move.
