Working Hard in the Wrong Direction: The Cardio Trap Nobody Warns You About

Strength as the foundation. Everything else follows.

There is a version of fitness that looks like dedication but is actually just noise. I lived in it for years.

In my late thirties I was doing 10 to 12 group fitness classes a week. Body Pump, Body Combat, Body Attack, GRIT. If it was a Les Mills class, I was there. Sometimes twice a day. I thought more was better. I thought if I just kept showing up, kept sweating, kept pushing, I would eventually get the results I wanted. I was wrong.

The thing that finally made me stop and pay attention was not exhaustion, although there was plenty of that. It was a layer of abdominal fat that would not shift no matter how many classes I did. I felt bloated. I felt stuck. And I could not understand why, given everything I was putting in, my body was not responding. I was working as hard as I ever had. The results were going in the wrong direction.

Why More Doesn't Equal More

Here is what I have since learned about the inverse relationship between volume and results.

Most cardio-heavy group classes are exactly that: cardio-dominant. And while cardio has its place, when you overdo it, the body does something counterintuitive. It clings to fat and starts breaking down muscle instead. Women over 30 lose approximately one pound of muscle mass per year without deliberate resistance training. Pile excessive cardio on top of that and you accelerate the problem rather than solve it.

There is also the cortisol factor. Chronic high-volume training keeps cortisol elevated. And elevated cortisol, particularly over time, drives fat storage directly to the abdomen. That layer I could not shift was not a willpower problem. It was a stress response. My body was under constant physical stress and it was holding on for dear life.

The third piece is adaptation. The body is extraordinarily efficient. Give it the same stimulus week after week and it stops responding. What felt hard in month one becomes maintenance by month six. The scale stops moving. The shape stops changing. Not because you are not working hard enough, but because your body has simply adjusted to the load.

What Changed

A coach eventually helped me see what I could not see myself. I needed to step back from the volume, prioritise strength training, and give my body actual time to recover.

That shift changed everything. Not overnight, and not dramatically at first. But consistently, over months, things started to move. The abdominal layer that had been stubbornly present began to reduce. My body composition shifted. My energy stabilised. I stopped chasing volume and started chasing progress.

The Takeaway

I am not here to tell you to quit cardio. I still do it. But the cardio I do now looks nothing like what I was doing in my thirties. Gone are the long, steady state sessions where everything just ticks along at a comfortable pace. What replaced them are shorter, sharper efforts. HIIT, intervals, conditioning work that spikes the intensity and then lets you recover. That kind of cardio works with your body rather than against it.

The problem was never cardio itself. It was the volume, the relentlessness, and the fact that it was doing all the heavy lifting while strength training sat on the bench.

Whether you are in your thirties, forties or beyond, showing up consistently, working hard, and still not seeing the results you expect — the problem is probably not your effort. It is the balance. Your body at this stage needs to be challenged to build, not just to burn. Strength has to be the foundation. Cardio plays a supporting role, a sharp, purposeful one, but a supporting role nonetheless.

Switching to this combination also helped me navigate perimenopause without the weight creep that catches so many women off guard. Both strength training and HIIT trigger what is known as EPOC, excess post-exercise oxygen consumption, the afterburn effect that keeps your metabolism elevated for up to 24 hours after you finish training. Steady state cardio simply does not do that. So while I was doing less in terms of volume, my body was actually working harder for longer after every session.

Not despite doing less cardio. Because of it.
