Cardio Every Day but Not Losing Weight?

Usually because cardio on its own doesn't give your body a reason to keep muscle, and muscle is what changes your shape after 40. In our experience, daily running or spinning tends to work against you when it takes the place of strength training and comes with too little food. Keep the cardio you enjoy. Add strength. Eat enough.

You're clearly not short on discipline.

You're up early. You show up every single day.

That effort just needs a better target.

Why isn't all that cardio changing your body?

Here's the thing.

For most of the women we talk to, cardio is the default. Running. Spin class. The treadmill. The elliptical with a show on.

Chris explains it like this: women reach for cardio because nobody ever showed them what else to do.

And for a while, it probably worked. In your 20s and maybe your 30s, a few more runs and a little less food usually did the trick.

After 40, that stops being enough.

Long, steady cardio uses energy while you're doing it. What it doesn't do is give your body a reason to hold on to muscle. And muscle is what gives you shape, strength and the toned look most women are actually after.

So you can be fitter than you've ever been, with a body that looks and feels exactly the same.

A lot of women describe it as spinning their wheels. Literally.

If you're also stacking classes and HIIT on top of everything, start with why working out 4 to 5 times a week isn't changing anything. This page goes deeper on the cardio part.

So is cardio making it worse?

Honestly? On its own, usually not.

Where we see it work against women is when it comes as part of a pattern. Here's what usually shows up together:

Cardio replaces strength. Lots of miles or rides, very little lifting. Your body gets plenty of practice moving and very little reason to keep muscle.
Food doesn't match the effort. A daily run or spin class on a smoothie and a salad. In our experience, that tends to drive up hunger and fatigue more than it drives down fat. Here's what happens when you're eating too little.
Cardio becomes how you earn your food. A lot of women tell us they finish a strength workout and still feel like they need the treadmill, because they haven't "burned enough." That math keeps you on the hamster wheel.
Recovery gets squeezed. Early alarm, hard session, every single day. In our experience, a body that never gets a day off tends to just feel tired.

You don't have to earn your food on a treadmill.

Your body needs it whether you ran today or not.

One quick note. If your doctor or physio has you doing cardio for a specific reason, keep following their advice. A good coach works around it.

Do I have to give up running or spin?

No.

Can we please stop pretending the only options are "run every day" or "never run again"?

If your morning run is your headspace, your quiet hour, the thing that makes you feel like you, keep it.

What we ask is that you build a few things around it:

Strength first. Resistance training is what Chris calls "the foundation and heartbeat" of everything we do. If you only have time for one workout, make it strength.
Walks count. Easy walks are great. Keep them.
Conditioning in small doses. Shorter, harder conditioning workouts have a place once or twice a week.
Enough food to fuel it all. Especially protein, at most meals.

Your coach looks at your whole week with you and helps you decide where your runs or rides fit.

And if pulling back even a little feels like a loss, that's completely normal. We hear it all the time. For a lot of runners, the run is about so much more than fat loss.

Most women come to us wanting to lose weight. What they actually want to lose is fat.

For that, strength is the foundation. Your run gets to be the part you enjoy.

What does a week look like instead?

Here's how it works in our 8-week 35+ Metabolic Reset:

Five workouts a week, about 50 minutes each. Three strength, two conditioning, and one of the conditioning days is optional.
At home, follow-along video. A set of dumbbells, a Swiss ball and some fabric bands. Chris coaches you through every session with modifications.
Workouts that build. The key movements get a little heavier or a little harder over the weeks, so your muscles have a reason to change.
A nutrition plan that fuels it. Real food, built around your schedule. No calorie counting, no food scales, no macro tracking.
A coach who's lived it. A PN-certified coach, a woman over 40 who has done the Reset herself, with weekly check-ins and direct access in between.

All in, it's about 4 to 5 hours a week, including food prep and check-ins.

For a lot of the daily runners and spinners we talk to, that's about what they're already putting in.

The difference is where it goes.

How will you know it's working?

Watch more than the scale.

When you add strength and start eating enough, the scale can be slow while your body changes underneath it. Here's why the scale can sit still while your clothes fit differently.

Instead, watch for:

Your clothes. Waistbands and jeans usually tell the truth first.
Your strength. The weights that felt heavy in week 1 often feel easier by week 6.
Your energy. Fewer afternoon crashes, fewer "I'm just tired all the time" days.

We've helped 1,000+ women lose 10 to 20 lbs of fat in 8 weeks.

Plenty of them were runners and spin regulars when they found us.

Ashley was running and nothing was working

Ashley was 44, a runner with a demanding career and three kids. She was running and eating well, and nothing was working anymore. In her video with me, she shares what changed.

Ready to give all that effort somewhere to go?

You've already got the hardest part. You show up.

Now your body needs a plan that matches the work.

Start with the short video on our homepage at fortyfwd.com. It walks through why your body stopped responding after 40 and the method we use to change that.

If it sounds like you, apply for a call with Chris.

He reads every application himself. On the call, he'll look at your training week, runs and all, and tell you straight whether the program is the right fit. If it is, he walks you through the investment then, once you both know it's a fit.

Keep the run.

Add the strength.

Let's make it count.

Frequently asked questions

Why am I not losing weight even though I run every day?

Cardio on its own doesn't give your body a reason to keep muscle, and in our experience it often comes with too little food. Adding strength training and eating enough is usually what gets things moving.

Is cardio bad for women over 40?

No. Walks, runs and rides all have a place. In our experience, it only works against fat loss when it replaces strength training and comes with too little food.

Do I have to stop running to lose fat?

No. Keep the runs you enjoy, add strength training a few times a week and eat enough to fuel both. Your coach helps you fit it all into your week.

How much cardio should I do in perimenopause?

We build around strength first, then add conditioning once or twice a week, with easy walks welcome any day. If your doctor has given you specific advice about cardio, follow it.

What's better for fat loss after 40, cardio or weights?

In our experience, strength training. It gives your body a reason to keep and build muscle, which is what changes your shape, and cardio becomes a helpful extra on top.
