249. The Deficit Isn't the Finish Line: Maintenance, Building & Why You Can't Diet Forever 07.07.2026

If you've ever thought your goal was to stay in a calorie deficit for as long as possible, this episode is for you. In the last episode, we talked about calorie deficits: what they are, how they work, and why they're necessary for fat loss. But what most people never learn is what comes after the deficit. The truth is, a calorie deficit is just one phase of your fitness journey…not your...

248. Understanding the Truth About Calorie Deficits 30.06.2026

You've heard it before: "The only way to lose weight is a calorie deficit." And while that statement is technically true, it's also one of the most oversimplified pieces of fitness advice on the internet. In this episode, I'm breaking down what a calorie deficit actually is, why it's not as simple as "eat less and move more," and why some women may need to f...

247. Exercise, Fertility, and Pregnancy with Dr. Hannah Ryles 23.06.2026

In this episode, I’m joined by obstetrician/gynecologist Dr. Hannah Ryles to talk about exercise, fertility, pregnancy, and postpartum recovery. We cover how the right kind of movement can support fertility, hormonal balance, and metabolic health, as well as when exercise can become too much stress on the body. We also talk about what types of workouts are safe while trying to conceive, how to tra...

246. Q&A: Protein Goals, Fat Loss Calories, Deloads, and Gym Confidence 16.06.2026

In this Q&A episode, I’m answering some of the fitness questions you have sent in recently, and we are covering a lot of the things that tend to make women overthink their progress. We talk about protein and whether it’s possible to eat too much, how to find a fat loss calorie goal that actually works for you, and what to do if tracking macros brings out your perfectionist side. I also break d...

245. Understanding Body Recomposition | The Gym Confidence Series 09.06.2026

Most women think they need to lose weight to change their body… but what they actually want is body recomposition. In this episode of the Gym Confidence Series, we’re breaking down what body recomp actually means, why strength training changes your shape, and why the “toned” look so many women want actually comes from building muscle - not starving yourself or doing endless cardio. I also talk abo...

244. How to Structure Your Workouts Without Overthinking It | The Gym Confidence Series 02.06.2026

If building your own workouts feels confusing, random, or overwhelming… this episode is for you. A lot of people think they need more complicated workouts, more exercises, more sweat, or a “perfect” plan to see results. In reality - most people are overcomplicating fitness and making it way harder than it needs to be. In this episode of the Gym Confidence Series, we’re breaking down how workouts a...

243. What to Use at the Gym (Without Feeling Overwhelmed) | The Gym Confidence Series 26.05.2026

Walking into the gym can feel intimidating when you don’t know what anything does. Between the machines, dumbbells, barbells, cable stations and cardio equipment… it’s easy to feel overwhelmed before you even start. A lot of women avoid the gym completely - not because they aren’t capable - but because they feel like everyone else knows something they don’t. In this episode of the Gym Confidence S...

242. Gym Lingo 101: Terms You Need to Know to Feel Confident in the Gym | The Gym Confidence Series 19.05.2026

Have you ever opened a workout and thought, “Okay… what the hell does that mean!?” Same. And honestly, this is exactly why I wanted to record this episode. This is the first episode in The Gym Confidence Series, where we are going to unf*ck the confusion around workouts, nutrition, and what it actually takes to see results. Let’s be real: the gym can already feel intimidating enough and then you a...

241. Client Story: How Julie Lost 30 Pounds, Built Muscle, and Changed Her Mindset 12.05.2026

I am so excited to feature one one of my Unf*ck Your Fitness clients, Julie, to talk about her fitness journey over the last three years! Julie came to me feeling frustrated, overwhelmed, underfed, and stuck. She had recently changed jobs, was navigating a new ulcerative colitis diagnosis, had gained weight, and knew she wanted to feel like herself again…but she had no idea where to start. We talk...

240. Q&A: Bloating & Gut Support, Glute Growth, Deload Weeks, Fasting and GLP-1s 05.05.2026

In this Q&A episode, I’m answering some of the questions you have sent in recently, and we are covering a little bit of everything. We talk about what I personally use for bloating and gut support, the smart scales I’ve used, and the app I use regularly for tracking food and macros. I also share what my deload weeks look like, especially because I do have to train a little differently and real...

239. Creatine, Aminos, and Why Muscle Matters More Than Ever with Liz Plosser 28.04.2026

In this episode, I’m joined by Liz Plosser to talk about essential amino acids, creatine, protein, aging, and why muscle matters so much for women. We break down the difference between protein powder, creatine, and EAAs, talk about why recovery and muscle preservation become even more important as we age, and get into the bigger picture of supporting your body well in every season. This conversati...

238. How to Stop Obsessing Over the End Result 21.04.2026

In this episode, I’m talking about why obsessing over the end result can actually pull you further away from the progress you want. I see this so often with my clients. Obsessing over the end result and not focusing enough on the small wins or daily tasks. It is good to have goals. It is good to have a vision and a plan. But so often, we get so focused on where we want to be that we lose sight of...

237. Straight Sets, Supersets, and Circuits: What’s Best for Body Recomp? 14.04.2026

Not all workouts are built the same - and if your goal is body recomposition, that matters. In this episode, I’m breaking down the difference between straight sets, supersets, and circuits so you can better understand what each one is, what each one is good for, and how they actually impact your results. A lot of women have been taught to think that the “best” workout is the one that leaves you th...

236. The Truth About Rest Days and Muscle Growth 07.04.2026

If taking a rest day makes you feel guilty, anxious, or like you’re going to lose progress… this episode is for you. In this episode, I’m talking about the mindset shift I had to make around rest days, recovery, and what actually helps your body change. I used to believe taking a day off would make me gain weight, lose momentum, or somehow fall behind. A rest day meant that “I failed the plan”  A...

235. Why Diets Work…But Still Keep You Stuck 31.03.2026

Why do so many diets seem to work at first… but still leave women stuck? In this episode, I’m breaking down the difference between following food rules and actually understanding nutrition. From Beachbody containers to Weight Watchers points and other simplified diet systems, I’m talking about why these methods can create short-term results while failing to teach women what their body truly needs...

234. My Thoughts on Alcohol, Fitness, and the Confidence to Make Your Own Choices 24.03.2026

In this episode, I’m sharing (in a very real and raw way) my honest thoughts on alcohol, fitness, and the confidence it takes to make choices that truly align with you. I’ve mentioned recently that I’m not drinking this year, and while this is a personal choice and a challenge I set for myself, it also opened up a bigger conversation around confidence, self-trust, and doing what feels right for yo...

233. Fitness Built More Than My Body 17.03.2026

In this episode, I’m sharing (in a very real and raw way - thanks to building confidence in myself)) what fitness has made me better at - not just physically, but in the way I live my life every single day. It was crazy to think back on all the ways I have become a different person!  What started as a conversation about workouts and body change turned into something much deeper: the skills, discip...

232. Real Life Q+A: Meal Timing, Measuring Progress, Progressive Overload, and How to “Do It All” 10.03.2026

In this Q&A episode, I’m answering some of the most common questions I get inside the Unf*ck Your Fitness community - and as usual,  I’m giving you simple, repeatable answers you can actually apply immediately. We’re talking about what to look at besides the scale, how to fuel around workouts without overcomplicating it, how to know whether it’s time to cut or stay at maintenance, and what pro...

231. 4 Mindset Shifts That Took Me to the Next Level with My Training and Macros 03.03.2026

If you want different results than the majority of people who feel stuck, frustrated, and constantly starting over, you HAVE to think differently than they do. These four mindset shifts didn’t happen overnight for me - they took TIME. I was imperfect at first (and still am), but over time, they’ve become a part of my identity.  When something becomes who you are, consistency stops feeling like a c...

230. Calories In, Calories Out Is Real…But It’s Only Part of the Equation 24.02.2026

Let’s talk about the phrase you see alllll over social media: calories in, calories out. According to the internet, it’s the *only* thing that matters. Just “eat less, move more,” and BOOM - problem solved. But…there’s a WHOLE lot of “fine print” that gets skipped over here. If you’ve ever felt like CICO “doesn’t work” for you, this episode is going to clear it up! Yes, calories in, calories out I...

229. What Training Volume & Intensity Actually Mean 17.02.2026

If you’ve ever thought, “Well, I guess I can’t progressive overload because I don’t have heavier weights,” this episode is for YOU. We’re talking about training volume, progressive overload, and why lifting heavier isn’t the only way to make progress.  Yes - access to a gym and heavier weights is great! But…it’s not required for results.  What actually matters? The amount of MEANINGFUL work your m...

228. Fitness Q&A: Strength Training, Cardio Timing, Body Recomp During Perimenopause & More 10.02.2026

Today’s episode is another fun Q&A pulled straight from my Instagram community! I received quite a few questions related to fitness and workouts, so I wanted to dive deeper into them here.  From belly fat myths, to cardio timing and body recomposition in perimenopause, this one is ALL about cutting through the confusion, and focusing on what actually matters on your fitness journey.  You shoul...

227. Your Body Is NOT Amazon Prime - Stop Expecting Instant Results 03.02.2026

I’m just going to say it… Your body is NOT Amazon Prime.  You don’t hit “order” on macros and wake up with your dream body 2 days later! Honestly, this expectation is why SO many people keep quitting. I see and hear it constantly from ladies: they track their macros for a couple of days (maybe a week), don't see the scale move, and immediately decide “nope - it’s not working”.  But…let’s be r...

225. Set Your Standards So High People Think You’re Crazy 20.01.2026

January can feel heavy. Life is busy, schedules are packed, energy is low, and it’s easy to fall into that “blah” headspace. Instead of lowering the bar or going into survival mode though, this episode is a reminder that this is actually the PERFECT time to raise your standards. Yep - even if people think you’re a little crazy for it! High standards make people uncomfortable. They don’t always mat...
