5 Biggest Fitness Myths (That Are Holding You Back)

5 Biggest Fitness Myths (That Are Holding You Back)

There’s more information available than ever.
And somehow, more confusion than ever.

Most people aren’t failing because they’re lazy.
They’re stuck because they’re following bad advice.

Let’s break down the 5 biggest myths I see all the time and what actually matters.

1. “You Need to Cut Carbs to Lose Weight”

Carbs have been blamed for fat gain for years, but they’re not the problem.

When you eat carbs, your body stores them as glycogen in your muscles and liver. Alongside that, you also store water. This is why when people cut carbs, they often see a quick drop on the scale. It’s not body fat, it’s water and glycogen.

Fat loss comes down to a calorie deficit over time.

You could eat:

• High carb and lose weight

• Low carb and lose weight

• Or overeat both and gain weight

Carbs actually help:

• Better training performance

• Higher training intensity

• Improved recovery

When you remove them completely, most people feel flat, weak, and end up struggling to stick to the plan.

What actually works:
Keep carbs in, focus on total calories, prioritise protein, and build a diet you can sustain.

2. “You Have to Do Cardio to Lose Fat”

Cardio is often seen as the main tool for fat loss.

It’s not.

Fat loss is driven by a calorie deficit. Cardio is just one way to help create that deficit.

The issue is people massively overestimate how much cardio actually burns.

For example:

• 30 minutes on the treadmill might burn 200–300 calories

• That can be undone in minutes through food

On top of that, doing loads of cardio can:

• Increase hunger

• Reduce recovery from strength training

• Lead to doing more but getting less results

That doesn’t mean cardio is pointless. It’s great for:

• General health

• Fitness

• Increasing daily activity

But it shouldn’t be your main strategy.

What actually works:
Use steps and general activity as your base, strength train to maintain muscle, and use nutrition to control the deficit.

3. “Lifting Weights Will Make You Bulky”

This is the one that holds the most people back, especially beginners.

The idea that you’ll suddenly become “bulky” from lifting weights a few times a week isn’t grounded in reality.

Building muscle is a slow process.

To actually gain a noticeable amount of muscle, you need:

• Progressive overload (getting stronger over time)

• Enough calories (often a surplus)

• Sufficient protein

• Consistency over months and years

Even in optimal conditions, muscle gain is gradual.

For most people:

• Beginners might gain a small amount of muscle in the first few months

• After that, progress slows down significantly

You don’t accidentally wake up looking like a bodybuilder.

What actually happens when you lift weights:

• You build some muscle

• You lose body fat (if in a deficit)

• Your body composition improves

That’s what gives the “toned” look people want.

And here’s the key point most people miss:

“Bulky” isn’t caused by lifting weights. It’s usually a combination of higher body fat levels and lack of muscle definition.

If someone feels bulky after starting the gym, it’s often because:

• They’re holding more glycogen and water (normal)

• They haven’t reduced body fat yet

• They’re more aware of their body

Muscle itself is dense. Adding muscle while reducing fat typically makes you look smaller, not bigger.

Also worth noting:

• Women, in particular, don’t have the hormonal profile (lower testosterone) to build large amounts of muscle quickly

• Most people struggle to build muscle even when they’re trying to

What actually works:
Lift weights with intent, follow a structured programme, and give it time. The result is a leaner, stronger physique not bulk.

4. “You Need to Train Every Day to See Results”

More training doesn’t automatically mean more progress.

In fact, doing too much often leads to worse results.

Training is the stimulus. Recovery is where progress happens.

If you’re constantly training hard with no recovery:

• Performance drops

• Fatigue builds up

• Injury risk increases

• Motivation falls off

You end up stuck in a cycle of doing more but progressing less.

Consistency beats intensity every time.

Three to four well structured sessions per week, where you’re:

• Progressing lifts

• Training with intent

• Recovering properly

…will outperform someone doing random workouts every day.

What actually works:
Train hard, recover properly, and stay consistent over months not days.

5. “The Scale Is the Best Way to Track Progress”

The scale is useful, but it’s limited.

It only tells you your total body weight, not what that weight is made up of.

Day to day fluctuations are completely normal due to:

• Water retention

• Salt intake

• Glycogen levels

• Hormonal changes

• Stress and sleep

You could be doing everything right and:

• The scale doesn’t move

• Or even goes up

That doesn’t mean you’re not progressing.

If you’re:

• Getting stronger

• Looking leaner

• Clothes fitting better

…then you’re moving in the right direction, regardless of the scale.

Relying on one metric is where people go wrong.

What actually works:
Use multiple indicators:

• Progress photos

• Measurements

• Gym performance

• Consistency

That’s how you get an accurate picture.

The Reality

Most people don’t need a new plan.

They need to stop jumping between extremes and focus on what actually works.

• A sustainable calorie deficit

• Structured strength training

• Enough protein

• Consistency over time

Simple doesn’t mean easy, but it does work.
