Why Your Body Composition Matters More Than the Number on the Scale

At 4D Gym in South Melbourne, one of the first things we do with new clients is an InBody scan. Why? Because it gives us an accurate breakdown of body composition—muscle mass, fat mass, and water retention—not just your total weight.

If you’ve been relying solely on the scale to track progress, it’s time to rethink your metrics. Because when it comes to real results, what your body is made of matters far more than how much it weighs.

Let’s unpack why body composition is a game-changer—and how it shapes the way we design training at 4D.

Why the Scale Is Misleading

Most people step on the scale and assume:

• Up = bad

• Down = good

But here’s the catch: that number tells you nothing about what’s changing inside your body.

You could lose 5kg and be weaker, flabbier, and metabolically slower if that loss came from muscle.

You could gain 3kg and look tighter, leaner, and more energetic if it’s quality muscle mass.

The number doesn’t matter unless you know what’s underneath it.

This is why our free consultation and InBody scan is such a valuable starting point—it helps you track real progress.

Muscle vs. Fat: The Real Difference

Muscle is dense, lean, and metabolically active. Fat is not.

Here’s what that means:

• Two people can weigh the same but look drastically different

• More muscle = more calories burned at rest

• More muscle = tighter shape, better posture, and joint support

• More muscle = better blood sugar regulation, improved mood, and lower injury risk

So if your goal is to look lean, move well, and feel confident, muscle—not weight—is your best friend.

Our private personal training and group strength sessions are designed to prioritise muscle development and metabolic health, not just calorie burn.

Body Recomposition: Lose Fat and Gain Muscle

This is where things get exciting. You don’t need to lose 10kg to transform your physique—you need to lose fat and build muscle at the same time.

This process is called body recomposition, and it’s exactly what our programs are built to support.

We focus on:

• Heavy compound lifts to stimulate muscle growth

• Personalised nutrition advice to support fat loss and recovery

• Smart programming that balances stress and adaptation

• Regular scans and check-ins to ensure measurable progress

You won’t just see the difference—you’ll feel it in your energy, sleep, strength, and confidence.

The Role of Strength Training in Body Composition

Strength training is the foundation of effective recomposition. It:

• Signals your body to hold onto muscle while in a calorie deficit

• Elevates metabolism for hours post-session

• Improves hormonal balance (like insulin, cortisol, and testosterone)

• Protects bone density and joint function as you age

This is why we structure every session at 4D Gym South Melbourne around progressive overload—not just variety or random intensity.

Whether you’re in a small group PT session or working 1:1 with a coach, the focus is always on long-term strength and composition improvements.

Why We Scan, Track, and Adjust

We use InBody scans because they provide:

• Skeletal muscle mass (not just “lean body mass”)

• Body fat percentage and visceral fat levels

• Segmental muscle breakdown (arms, legs, trunk)

• Water balance and inflammation indicators

This data helps us adjust your program intelligently—no guesswork, no wasted effort.

Clients who scan every 4–6 weeks are more motivated, more consistent, and better able to spot trends and plateaus.

If you haven’t scanned lately, it’s time to see where you’re at.
