Core Training: The Foundation of Strength

Core training is one of the most valuable things you can invest in, whether your goal is to feel stronger, move without pain, improve your lifts, or yes, work toward a flatter stomach or visible abs.

Your core is involved in almost everything you do. From getting out of bed, unloading the dishwasher and playing on the floor with your child, to push-ups, squats, deadlifts and carrying heavy groceries. It is the central link between your upper and lower body and plays a key role in how efficiently and safely you move.

In this blog, we go beyond the idea of core training as just abs. You will learn what the core actually is from an anatomical point of view, how it transfers force through your body, why it protects your back, and how proper core training improves both daily movement and performance in the gym. We will also cover what good core exercises look like, what bracing really means, and how to apply core tension in a way that matches the task you are performing.

If you want a body that feels strong, resilient and capable, this is where it starts!

How to Stay Fit During the Holidays

The holiday season is warm, joyful and full of celebration. It is also a time when routines shift, gym schedules change and indulgent dinners seem to appear every other day. Two days of feasting will not undo your progress, but several weeks of unstructured eating, drinking and skipped workouts can leave you feeling sluggish and disconnected from your body.

With the right mindset, a bit of planning and a few supportive daily habits, you can enjoy the season to the fullest while still feeling strong, energised and in control.

The Truth About Alcohol: What Science Really Tells Us

Ever noticed how one glass of wine can feel like a stress reliever after a long day — but somehow leaves you feeling foggy, tired, or even anxious later in the week? Alcohol has been part of human culture for thousands of years, celebrated as a social glue, a reward, a ritual. Yet beneath that friendly glass lies a surprisingly complex biological story — one that every health-minded person deserves to understand.

In this blog, we’ll explore how alcohol truly affects your body and mind — from your sleep, hormones, and mood to your gut health, long-term wellbeing, and even your metabolism. We’ll uncover the science behind that morning-after anxiety, the myth of “healthy red wine,” and why skipping alcohol might be the best thing you can do for your performance, focus, and energy levels.

This isn’t a lecture. It’s your practical, science-based guide to what really happens when you drink — and how to make mindful choices that support your goals.

Get HYROX Ready: Build Endurance, Strength, Confidence, and Strategy for Your First (or Fastest) Race

I was first introduced to HYROX back in 2021 when my former coach Simon competed individually at HYROX in the RAI Amsterdam. My reaction? “This is NOT for me. It’s way too much running!” Flash forward two years and guess what? I completed my first HYROX Individual Pro. Oh, how things change! Since then, I’ve also competed in HYROX Doubles with my husband Kevin—an incredible experience that pushed us both. My personal focus has been on improving my running speed, since my CrossFit background gave me a solid advantage in the functional exercises. My personal and professional experience helped more than 10 Dymphy Fit athletes to perform in a HYROX event in the last years!

In this blog, you’ll learn what HYROX is, why it’s so popular, how to train for it, what to expect on race day, and how we support our athletes at Dymphy Fit to get competition-ready—both physically and mentally.

Everything About Fat Loss: Answering Your Burning Questions

Ever feel like fat loss is a mysterious process that your body performs behind closed doors? You’re not alone! When clients come to me, they often have the same puzzled expressions: “What exactly happens when I lose fat? Am I burning fat during my workout? Is the fat on my plate the same as the fat on my hips?”

If you’ve been wondering about these questions too, you’re in the right place. In this blog, I’m pulling back the curtain on the science of fat loss to finally make things click.

Recover Right: Why Recovery Matters More Than You Think

Recovery isn’t just sitting on the couch watching Netflix (though sometimes it can be!). It’s a deliberate practice that deserves as much attention as your hardest training sessions. Let me explain why recovery could be the game-changing element your fitness journey has been missing.

Recovery is the process that creates an internal environment for your body to rebuild and remodel tissues to be bigger, stronger, and faster. Think of it as the quiet construction crew that comes in after hours to repair and upgrade your body’s infrastructure.

Training with Your Menstrual Cycle: Optimizing Performance

For decades, the menstrual cycle has been treated as irrelevant to athletic performance, or worse, as an inconvenience to be ignored. But what if understanding your cycle could be the key to unlocking your full athletic potential?

This guide isn’t just for women. Coaches, training partners, and male athletes who work with female athletes can benefit immensely from understanding these natural fluctuations. Just as a sailing crew needs to understand shifting winds to navigate efficiently, anyone coaching or training with women needs to appreciate how hormonal changes affect performance and recovery.

By learning to work with your body’s natural rhythms rather than fighting against them, you can transform what might have felt like a monthly obstacle into a strategic advantage. Think of it as having access to your body’s internal training calendar—knowing when to push hard, when to focus on technique, and when to prioritize recovery based on biological cues rather than arbitrary training schedules.

Protein Power: Your Weapon for Fitness Success

Protein is the foundation of life! It plays a crucial role in nearly every bodily function. From supporting muscle growth to optimizing metabolism, consuming enough protein is essential for health, performance, and longevity. Think of protein as your body’s building blocks—without enough of them, your fitness goals are like trying to build a house without bricks! This blog teaches you the importance of protein, how much you need, what that looks like on your plate and the best timing around your workouts.

Struggling with Consistency? Here’s How to Make Fitness Stick

Remember those New Year’s resolutions you made with such enthusiasm just weeks ago? The gym membership, the workout plans, the commitment to transform your fitness—they all started strong. But now? Things might already start to slip. That initial motivation is fading, and consistency feels like an uphill battle. You’re not alone.

Consistency is simple, but not easy. Think of it like building a house: you wouldn’t try to construct it in one marathon session. Instead, you lay each brick carefully, day after day, until you have a strong foundation and sturdy walls. At its core, consistency is showing up. It’s about making a commitment to yourself and following through, even when motivation wanes and excuses pile up. Doing the simple stuff consistent, is difficult.

In this guide, you’ll discover practical, actionable strategies to transform your approach to fitness, overcome mental barriers, and build habits that actually stick—turning your fitness goals from a fleeting resolution into a sustainable lifestyle.
