Cardio: Do You Really Need Cardio To Lose Weight? (KL Trainer Explains)

What People Get Wrong About Cardio For Fat Loss

Cardio is like that good-looking bully you had back in school, or even in your workplace now: it's got a reputation problem.

Some people treat it like the holy grail of fat loss. Endless running, sweating buckets, chasing that calorie burn like it's the only thing that matters, and the only thing that will ever matter.

Then you have the group of people that's just . . . Cardio? No.

"Cardio kills gains."

"Lifting is enough."

"I'm too big for cardio."

They act like the treadmill or the spin machine is some kind of muscle thief waiting in the corner, ready to strike the moment their guard is down.

Well, your friendly neighbourhood trainers are here to tell you that both sides are wrong.

Cardio isn't the hero, nor is it the villain. It's just a tool. And like any tool, it works brilliantly when used correctly . . . and backfires when abused.

Myth #1: More Cardio = More Fat Loss

This is the part where most people go off track.

Yes, cardio burns calories. That's a true fact. But, as we all learnt at some point or another in our lives, more isn't always better. When you pile on excessive cardio, especially while eating too little, your body doesn't just burn fat. It starts adapting and you might just find that you're not getting the results you expected.

Bet you didn't see that coming. Here's what happens:

• Your energy drops

• Your recovery slows down

• Your workouts feel weaker

• Your body holds onto fat as a survival response (slower metabolism)

Worse, you risk losing all that muscle you worked so hard to get. And muscle is what keeps your metabolism higher in the long run. So instead of becoming a lean green fighting machine like you'd always dreamt of becoming, you end up smaller, softer, and exhausted. That's not fat loss. That's burnout with extra 5K steps.

Myth #2: Cardio Is The Only Way to Lose Weight

Fat loss doesn't come about by you sweating rivers each day through runs or HIIT moves. It comes down to a calorie deficit. Cardio can help create that deficit, but it's not the only way.

Strength training plays a huge role. It builds muscle, improves metabolism, and shapes your body. If you rely solely on cardio, you might lose weight, though not necessarily in a way that looks or feels good.

Think of cardio as support, not the foundation.

Myth #3: If You Don't Do Cardio, You Won't Lose Fat

We'll be honest with you, when we first started training, this exact myth was living rent free in our heads. The good news is, we've learnt our lesson and we're here to tell you that: you can absolutely lose fat without traditional cardio, provided you meet a few criteria first.

Firstly, your nutrition has to be under control. Whole, healthy foods in balanced portions. Following that, you have to be sure that your daily movement includes some decent steps or some form of physical activity. Moving from your sedentary day job to your sofa at home to continue that sedentary marathon is a big no-no. Lastly, you need to be sure that your strength training is consistent. The kind of consistency that's so ingrained into you that it's become a habit.

The good new is, with these, fat loss will still happen.

The bad news is, skipping cardio will make things harder for you. It's like choosing to push your car instead of turning the engine on and driving it. Possible, but unnecessarily difficult.

Why Cardio Feels So Hard (And Why People Hate It)

We're going to lay all our cards on the table here, guys. Cardio has a branding issue. It's repetitive. It's uncomfortable. It doesn't give you the immediate "reward" feeling that lifting weights does.

When you lift, you feel strong. You probably also think you look like The Hulk when you're hitting a new PR. When you do cardio, you feel your lungs filing a complaint and your shins begging you to take a break. There are a few reasons why this is so:

1) It's Mentally Draining

Running in place or staring at a wall while cycling can feel like time slows down.

2)It's Physically Uncomfortable

Your heart rate spikes. Your breathing gets heavy. Your body is literally telling you to stop.

3) People Start Too Intense

Most beginners go too hard, too fast. They turn cardio into punishment for those extra cookies from lunch time instead of progression.

No wonder they hate it.

How To Actually Use Cardio for Fat Loss

There's a sweet spot to hit for this: moderation. You want enough cardio to support fat loss, but not so much that it destroys recovery. A simple structure would look like this:

• 2-4 sessions per week

• 20-40 minutes per session

That's it. You don't need to live on the treadmill or pay for "fat loss programs that guarantee results in 3 weeks".

Best Types of Cardio (Based on Lifestyle and Age)

Not all cardio has to look like running until your soul leaves your body. Here's what we recommend:

For Beginners or Older Individuals

• Walking

• Incline treadmill walk

• Light cycling

Walking, especially, is underrated. It's low impact, easy to recover from, and sustainable long-term.

For Younger or More Active Individuals

• Jogging or running

• Stairmaster

• Skipping rope

• Sports (badminton, futsal, basketball)

• HIIT (in moderation)

The key is finding something you don't dread. Cardio shouldn't feel like a chore.

Cardio + Nutrition: Where Most People Mess Up

This is the dangerous combo that you'll want to avoid:

• Too much cardio

• Too little food

It sounds like a fast track to fat loss. Tempting to try on account of how logical it sounds. In reality, it's a fast track to feeling terrible.

When you under-eat and over-train:

• Your body conserves energy

• Your performance drops

• Your cravings increase

• Your recovery gets worse

Eventually, progress stalls or reverses and you're left even more confused than when you first started. Trust us, fat loss should feel challenging, not punishing. Just because you're losing fat, or trying to lose fat, you still need enough protein to preserve muscle, enough carbs for energy, and enough calories to function.

Cardio is a complement. It should support your diet, not compensate for a bad one.

Why Recovery Matters More Than You Think

Cardio isn’t just about the workout or the amount of calories you see burnt on the screen after 40 minutes of trudging your way up that incline treadmill. It’s about how well you recover from it.

If you’re constantly tired, sore, and unmotivated, your body isn’t adapting. It’s struggling, and not in a good way.

Good recovery always includes these four pillars: proper sleep, adequate calories, rest days, and managing stress.

As is it with strength training, so it is with cardio: progress doesn’t happen during the training itself. It happens after, when your body rebuilds.

So . . . Friend or Foe?

Cardio is the best of both worlds: it's friend and foe, depending on how you use it.

If you go down the path of light (using cardio correctly), cardio supports fat loss, improves heart health, and increases your endurance for any physical activity.

If you choose the path of darkness (using cardio incorrectly), you'll feel drained, you'll have slow recovery, and you'll lose muscle.

The difference here isn't the cardio itself. It's the strategy behind it.

Final Thoughts: Balance Always Wins

Don't fear cardio. Don't worship it either. Keep your approach a balanced one: strength training as your foundation, cardio as support, nutrition as the driver, and recovery as the glue that holds it all together.

Use cardio wisely, and it'll work for you. Abuse it, and it'll quietly work against you. Most importantly, pick something you can actually stick to, because the best cardio plan in the world won't do much if you're going to be hating every second of it.
