Hi there, I’m Anne Marie. (“AM” for short.)
I’m a mom to two boys (and two girl kitties—for balance), wife to one husband, writer, podcaster, and personal trainer/accountability coach.
And I currently reside in the space referred to as “mid-life”.
My reason for creating Aging Fiercely is to do my all-time best at offering up what I’ve learned as I head into the great gap of — wait… what happens when my kids don’t need me as much anymore!? Who am I now? What do I even want? Where did my boobs go? Oh wait, I see them, down by my knees. 😳
All are welcome here — you don’t have to be in the thick of midlife to decode my work, but so you’re not wasting your time or throwing me the side-eye, those who may gain the most from being here are:
The bewildered mid-life mom who isn’t sure how she got here—wasn’t I just living in the city, working a bullsh*t corporate job I hated while having the time of my life going to happy hour every Thursday night with my five roommates? Yes, you were. But you’re here now, and it’s ok. The time has come to put you back on your list, and don’t worry, the kids will be fine—they actually prefer you not notice them lest you gross them out trying to hug them. (Me saying to my kids one time: You know… I used to be SO MUCH fun!)
The fed-up mom who is exhausted from TRYING. SO. HARD. to squeeze in her workouts, but knows she can never compete against the logistical nightmare that is chauffeuring her kids to baseball games, soccer practice, and violin lessons. I see you! Your time is now. (They still need us, just not in that “snuggle with me” kind of way. We’ll be fine.)
The frustrated mom who would rather shave her eyebrows off than have to watch one more YouTube Gen-whatever flash a gorgeous belly and say, And I still eat pizza! (But we’re not bitter about it!)
Women in search of real, relatable, and slightly humorous wellness advice from someone who has been there and is still working on aging fiercely!

I’m here to help you live in the moment, recognize your worth (and own it!), and take to heart that you’re capable of much more than you ever gave yourself credit for. (TRUTH!)
Is it possible for you? you ask. Obvs! That’s why I’m here—to get you feeling like this 👉 … that one time when my client did 10 push-ups and practically short-circuited from the shock. Like, wait, did I just do that? Me? The person who once considered rolling off the couch a core workout? Yes, YOU DID, QUEEN. And that moment? That *holy-sht-I-actually-did-that* feeling? That’s what’s waiting for you here.
All you have to be willing to do is:
See things in a different light
Tell a new story about yourself—and ditch the farty ones
Try something different.
Because we’ve all tried everything, and sometimes, nothing works. But when we…
Dig deeper (past the excuses, past the doubt, past the “I can’t”)
Ask better questions (like, “What if I don’t quit this time?”)
Push past the limits we think we have (most of them are BS anyway)
… that’s when we shatter the mold, shake off the nonsense, and start seeing ourselves for who we really are: capable, strong, and ready to torch every outdated belief we’ve been lugging around for way too long.
YOU FEELING IT? (Cue the Rocky theme song!)
Here’s what you can expect from me:
The Sunday Mail Drop ❤️ is my weekly love letter. I talk mostly about well-being, the power of accountability, how to build momentum, and how every change begins by paying attention to what’s going on in your mind!
I also dispense a healthy dose of what I’ve learned as a personal trainer and accountability coach for the last 15 years to help you create a healthier and happier life. And to feel firece in your body! 💃
Every Thursday, join in the fun that is the Aging Fiercely Podcast cocktail mixer. This weekly mixer is entertaining, conversational, and relatable as hell. It includes real stories from me and the many guests I have on—you’re sure to walk away with a glass full of ideas to marinate your olives in.
Here are a few awesome ones for you to get acquainted with:
Accountability Coaching: Because your goals deserve more than good intentions. I work with women in my 4-Week Accountability Program who are done struggling to make fitness, well-being, and their big life goals a priority. You don’t need another plan—you need someone to keep you on track, call out your excuses, and cheer you on like a hyped-up sports coach with a megaphone.
And guess what? It works. 💥
But don’t take my word for it—see what they had to say! (Right there 👇 below the subscribe button… wink wink )
Anne Marie brings new meaning to the words accountaibility coach. She became my mentor and literally watched out for me and followed up with me every single day.
She held me accountable and pushed me to achieve my goals. I am on track for what I wanted to achieve and will not hesitate to call her and ask for further help or direction.
She made me realize that sometimes we all need a little push but also some grace. I now speak to myself a little gentler and she taught me that! Very, very great and beautiful person to work with!
xoxo love ya!

Working with Anne Marie was such a positive experience! From the start, she was incredibly supportive, helping me set clear, achievable goals and keeping me on track every step of the way. Whenever I faced setbacks, she was right there to help me work through them without judgment, providing insightful guidance and encouragement that kept me motivated.
What truly stood out was her ability to help me see the bigger picture, reminding me of my long-term vision when I got caught up in the small challenges. Thanks to her dedication and expertise, I feel more confident in my ability to stay on course toward my goals. Highly recommend!

And if you’re here and not sure if you should be, here’s a small list of who I’m not for:
People who need real medical advice from a mental health professional—even though I dole out the advice in mass quantities, there are no doctors here.
Mean or rude people—we’re not meant to be friends, and that’s ok. (Or maybe we can be friends if you allow yourself to come out from behind your wall. 🤷🏻♀️)
You love politics and fear-mongering headlines. I just can’t…
In conclusion…
Please take a long and leisurely stroll around the gardens of verbiage here and pick out the stories that draw you in and resonate deeply.
Pick as many as you like, and if the urge strikes, please leave a comment or hit that little heart icon ❤️ so I know what tickles your chin hairs. Of course, this is completely optional, but I always appreciate it when you let me know you found something you feel was written just for you!
In case you want a bit more, here's an interesting fact about me:
I’m a sucker for guilty pleasure songs—as in the ones you can’t HELP but sing along to in the car when you’re alone but will never admit to anyone… except to complete strangers on the internet.
Hence, me sharing my top 3 guilty pleasure songs with you:
Holding Out for a Hero — because that scene in Footloose, when Kevin Bacon’s shoelace is stuck on the tractor pedal and HE’S GONNA DIE IF HE DOESN’T GET HIS FOOT LOOSE, but then he does (whew) and it’s all for the love of a girl who’s got some serious daddy issues.
Oops… I did it again — because anything Britney, I’m here for.
We Built This City — my favorite line is “…while Cody plays the mambo…” and I don’t even know if that’s what they say, but that’s how I sing it, and I refuse to Google it.
Where else can you find me?
If you’re dying for more of me, you can also find my podcast, Aging Fiercely, on Apple or Spotify, and I’m (sometimes) on Instagram @aging.firecely.
So that’s me in a super small nutshell of a nutshell.
Now tell me about you—but first, you’ll have to share your three guilty pleasure songs, and then we’ll go from there! (You can email me at amcostanzo@substack.com - oh, you thought I was kidding 😆?!)
❤️

Aging Fiercely is where we turn the midlife crisis into the midlife comeback! 👊Join the growing community of women who now do squats while waiting for their morning coffee to brew!
P.S.: Let me leave you with a little food for thought: How would you answer this question?
If I wasn’t afraid of people's response, what would I say “no” to immediately?
If you can answer that and share with me, it may trigger something loose inside you that’s been dying to be revealed for a long time. Try it!
