Stop Wasting Time: New Science for Better Results at Any Age
In this game-changing episode, I’m tackling one of the most confusing topics for women over 40—what type of exercise actually works for maintaining a healthy weight, strong bones, and vibrant energy as we age? Drawing from both my personal journey and decades of research, I’m exposing the outdated myths about cardio and weight training that might be holding you back from your best health. You’ll discover why the conventional wisdom about endless treadmill sessions could be sabotaging your results and learn about the surprising connection between grip strength and longevity. If you’re frustrated with your current fitness routine or worried about maintaining your independence as you age, this episode is your roadmap to building a stronger, more resilient body that keeps up with your vibrant life.
What you’ll learn:
- The shocking truth about muscle loss after 40 and what it means for your metabolism
- Why your grip strength could be the most important health metric you’re not measuring
- The game-changing research about VO2 max and longevity
- How to combine cardio and weights for optimal results at any age
- Simple strategies to prevent bone loss and maintain independence
- The most effective exercise sequence to transform your fitness routine
- Why the old “cardio-first” approach might be working against you

If you’re sick of spending all your time on the treadmill and not getting any results, or you’re afraid of the weight room, thinking you’re going to get bulky, you’re going to want to listen up. I’m going to talk about what actually works best for women in their 40s, 50s, and 60s and beyond, and what I wish I knew sooner so you can learn from my mistakes and get on the fast track to better fitness.
Now, when I was in grad school, no joke, we were taught, do not lift weights until you lose the weight. Everything back then was about LSD, long, slow distance, was the best thing for weight loss. In fact, they told us back then that if you couldn’t do at least 30 minutes of cardio, don’t even bother starting.
But you should be doing at least an hour a day. It was all cardio, cardio, cardio for calorie burning and fat burning and you had to be in your fat burning zone. You remember all of that? Now you’ve likely heard the opposite too. Don’t do cardio, it burns up your muscle. Don’t do cardio, it raises cortisol.
Don’t do cardio, it’s going to age you faster due to all the increased oxidative stress. Plus, cardio just makes you hungry. And what about weights? Can they make you bigger? I mean, you’re not really going to be burning fat like you do in a cardio workout. So what do you do? Okay, it’s time to cut through the confusion.
I’m going to share what you should be prioritizing for the best body composition and overall health. And let’s start with some stats and really what we want to avoid. So starting at around the age 30, you begin to lose. You don’t have to, by the way. But you will un left unchecked up to 1% of your muscle mass every year.
Up to two to 4 percent of your strength every year. That’s can you get the jar lid off the jar? Up to six to 8 percent of your power per year. That’s how fast you’re moving. Now grip strength. The reason I mentioned that jar is a great proxy for Overall strength. There was a study in 2017 that looked at grip strength and all cause mortality.
They reviewed 42 other studies. They looked at 3 million participants and it was published in the Journal of the American Medical Directors Association. And what they found was that lower grip strength is linked to higher risk of death and cardiovascular diseases. In fact, people with the lowest grip strength had a 50 41 percent higher risk of all cause mortality and a 63 percent higher risk of cardiovascular diseases compared to those with the highest grip strength.
Now, grip strength is a really good proxy for overall strength. You can check yours by using something called a hand grip dynamometer. We’ll put a link to how you can get one in the notes. It’s like, they’re like 30 bucks on Amazon. But the other way you can check your overall strength is by is a push up test.
Next thing, VO2 max. So, VO2 max is probably the best predictor of all cause mortality of anything. When you think about, you go to the doctor’s office to get all these labs done, you should be doing a VO2 max. So, 5-15 percent of your VO2 max, you start to lose. Every decade, starting at age 30. And what again, is VO2 max, it’s your body’s ability to use oxygen during exercise.
So we start to lose it again, like the others. We don’t have to lose it at the sharp decline you’re hearing about. So there was a 2016 observational study that was published in Mayo Clinic Proceedings, and it looked at the changes in cardiorespiratory fitness It’s measured by maximal oxygen uptake, that’s VO2 max, during exercise and how it affected your all cause mortality.
What the study found was that for each 1 mL per minute per kg increase in VO2 max, it was associated with a 9 percent reduction in the risk of death. And by the way, that is not a big increase to have that big of a reduction. And by the way, Again, poor VO2 max right now is being thrown about as the number one indicator of all cause mortality.
So this is definitely one that you’re going to want to know. And let’s talk about bone mineral density and hip fractures. So there was a study that showed that over 19 percent of patients over 65 who had a hip fracture died within the first year. And there was a cumulative mortality rate of over 54 percent within the first year.
Five years. And after a hip fracture, only 26 percent of patients regain independent living one year post injury. Many people, it changed the trajectory of their ability to live forever. So, we gotta ensure. That we’re holding on to our building muscle, better yet building, right, and increasing strength and power.
That we are supporting a really good VO2 max and that we’re keeping our bones strong and we’ve got good agility, balance, and flexibility so that we’re avoiding falls. Basically, we want to make sure that we’re doing the right exercises To be built to last and be able to play full out as we age. So the big question is, is that cardio or weights?
And what I say is it’s not either or. It’s really how you do these and what you prioritize. So I want to talk to you the benefits and then how you’re going to put it all together. So let’s first talk about the benefits of resistance training. So resistance training is anabolic. That means it builds you and it also builds your fast twitch muscle fibers.
So when we talk about anabolic, it’s going to raise testosterone and growth hormone, two very important anabolic hormones that go down as we age. It also is going to help build something called your fast twitch muscle fibers. We have on our body slow and fast twitch muscle fibers and then ones that are hybrids that can become one or the other.
As we age we tend to lose a lot more of those fast twitch fibers and those are more of that explosive strength and power and so that’s why we start to get Weaker and slower as we age. Well, resistance training can build back those fast twitch fibers. What’s cool, and what you probably wouldn’t have thought made sense, is you can actually improve your VO2 max with resistance training too.
So it’s good for your cardiovascular system. And by putting on more muscle, you’re going to improve your resting metabolic rate. Plus, the way you work out when you do resistance training creates a big oxygen debt. So you’ve got to do more after the exercise it’s called a metabolic cost. Your body’s going to spend more calories post exercise to recover from it.
So it’s improving your muscle size, your muscle strength, your muscle power. It’s going to help with your bone density because when you’re putting that stress on your bones by lifting weights, it helps them get stronger. And if you’re doing resistance training correctly, you’re also pulling in balance and flexibility and hopefully agility too.
Now what about cardio? Well, cardiovascular training is going to help your heart. It’s going to help your blood pressure. It’s going to burn a bunch of calories. It’s going to help your VO2 max. And if you’re doing cardiovascular training in a very specific way called high intensity interval training, this can also help with visceral adipose tissue, that bad fat around your abdominal area.
And the reason I really love high intensity interval training. is it’s going to boost growth hormone. It’s going to create a bigger metabolic cost and it’s very time efficient, but it is the best thing for improving VO2 max, especially done in very specific ways. And here’s one other cool thing that both, you’ll find both with resistance training and cardiovascular training, they actually can help control your appetite.
So do not worry about that urban legend. So when you hear this, you’re like, Oh, Well, I need to do both, but there’s specific things that you’re going to want to do with both. And I will tell you that ideally you want to prioritize that resistance training. But first. The very first thing you want to start with is making sure that you’re moving more.
It’s getting in that 8, 000 plus steps per day with 8, 000 being the floor, right? And ideally, you’re going for 12, 000 or more. Once you’ve got that done, that you’re tracking through using a tracking app, like, you know, one of the wearables onto an app, then add some intensity. Especially something like a rucking vest, a weighted vest or a weighted backpack, because that’s going to put that stress.
on your hips and your spine. That’s going to help with bone mineral density. So that’s the first part. And by the way, into those steps, we could add a little high intensity interval training too. Bonus. Now, once you’ve got your steps down, you know that you’re doing that every single day, that it’s a non negotiable.
The next thing you’re going to do is you’re going to add resistance training. And I like to say that you do resistance training,
