LET’S TALK ABOUT YOUR GOALS
I’ll go through your answers and we’ll talk more about your goals, your starting point and what type of coaching would suit you best.
I’LL BUILD YOUR PLAN
Once we get started, I’ll create a personalised plan based on you, your goals and everything we’ve discussed.
START YOUR JOURNEY
From there, we’ll work together towards your goals. I’ll be there along the way with feedback, support and adjustments whenever needed.
WHAT’S INCLUDED?
Your plan. Your goals. Your progress.
  • INDIVIDUAL APPROACH
    You’re unique, with your own starting point, lifestyle and goals - so your plan should never feel like a one-size-fits-all programme.
  • WORKOUT-PROGRAM
    • A combination of compound and isolation exercises designed to help you build strength and muscle
    • Thought-out structure, sets, reps and progression
    • Adapted to how many days you can realistically train
    • Warm-ups and cool-downs to prepare your body and improve your performance
    • Ongoing adjustments as you progress
  • PERSONAL NUTRITION PLAN
    • Calories and energy intake tailored to you and your goals
    • Easy, delicious recipes based on your food preferences
    • Multiple meal options within the same plan
    • Flexibility that makes your nutrition work with your everyday life
  • COACHING & SUPPORT
    You don’t have to figure it all out on your own. I’ll be there throughout your journey to help you stay motivated, know what to focus on and keep moving forward. Check-ins can be daily, weekly or monthly depending on what works best for you.
  • KNOWLEDGE YOU CAN TAKE WITH YOU FOR LIFE
    My goal isn’t just to give you a plan to follow. I want you to understand your training, nutrition and how to build discipline and sustainable habits over time.

CLIENT RESULTS
Real progress, real transformations. Every photo in this collection represents a small glimpse into the journeys my clients have taken through our coaching. Behind every result is a unique starting point, individual goals and consistent work over time.

Each transformation is different - but they all have one thing in common: becoming stronger, more confident and feeling better in your own body.


P.S. You can find more client transformations and feedback in my Instagram highlight “Clients”.

My clients, in their own words:
Jeanelle
Client for 3 years.
I am honestly so incredibly happy with everything you have helped me with. You have truly helped me improve my physique with your amazing training and nutrition plans, as well as your encouragement and the fact that you are always available to answer my questions.

None of your plans have ever disappointed me, and I can guarantee that I’ll continue working with you for a long time to come. And in my “after” picture on the right, I’m even wearing jeans - absolutely incredible results!

Ferda
Client for 2 years.
I have to say, wow - your programme has changed me so much! I’ve gained weight and built more muscle, and I’m so grateful to have you there helping me reach my goals.

You’re the best! (Only two months between the pictures.)
Elin
Client for 3 months.
It’s going incredibly well. I feel so much stronger and I’m doing so much better mentally too! I can lift heavy weights across so many different exercises - for example, 140 kg x 4 in hip thrusts, 15 kg x 8 on a single-arm dumbbell row, and so much more.

The gym has become like my second home, and I don’t think I’ll ever stop appreciating the support I get from you. I’m so grateful.

I would absolutely recommend you to anyone who feels lost and needs help developing both physically and mentally.
You’re the best!
Joesphine
Client for 3 months.
Hi lovely Mathilda! I think it’s been going so well. I absolutely LOVE the plan! All credit to you. I can already see and feel a difference, and it feels so amazing being able to increase the weights.
So excited for my next plan!

Client for 7 months.
The first picture was taken when I started the plan and the second one was taken today! I genuinely feel so much stronger in my body and I feel great.
I’m not the best at taking pictures from the right angles, but I think my glutes have maintained their size despite losing a lot around my waist.
Felicia W
Client for 2.5 years.
My experience with you, Mathilda, has been worth its weight in gold. I reached out to you after trying to lose weight and work out on my own. I had a very restrictive mindset around food and thought the only way to lose weight was to eat salad. How wrong I was!
I’ve been able to eat so much delicious food every day and have gained a completely new perspective on nutrition thanks to you. The training plan has also been incredible, with everything adapted to my goals and preferences.
You’ve always been so kind and quick to respond. You give clear answers and even send video tips whenever I’m unsure about an exercise.

I’ll always be grateful for the help you’ve given me.
Saga
Client for 3 months.
I’m extremely happy! The plan is very detailed, with lots of pictures as examples. The meal plan is great because you focus on good food and actually EATING. You’re always available when needed and respond quickly. I’m super happy!🥰
Esra
Client for 4 years.
Amazing person! You know what you’re doing, you know your job. I really trust you. Thank you, thank you!
Johanna C
Client for 3 months.
I love your recipes! The training has also been amazing. I don’t think I’ve ever had this much muscle soreness in my life… even though I trained the most when I was younger. My fiancé even laughed when I got out of bed this morning - I was walking like Quasimodo from The Hunchback of Notre-Dame haha!
Jenny A
Client for 3 months.
Such a great and caring coach who you can always reach out to without hesitation. You get quick feedback, and whenever you have questions or concerns, you always receive clear and helpful answers!

The training programs are very clearly structured and easy to follow and understand. A well-thought-out approach that makes it really enjoyable to follow your own fitness journey and see your progress. I couldn’t recommend you enough as an online coach!
Asia
Client for 3 months.
My experience of getting help from you, Mathilda, has been wonderful. You have always responded whenever I’ve had questions, and you work quickly and efficiently while really listening to me. I’ve genuinely felt heard and prioritised! Thank you for all your help.
Julia A
Client for a year.
I’m very happy with the help you’ve given me with both my meal plan and training program. You’re very attentive, encouraging, and dedicated to giving each person the best support possible.

I feel that I’m much more confident in my training today and that I’m more motivated than I’ve ever been before. Thanks to you, I’ve made progress in my training, especially when it comes to my technique.

I would definitely recommend you to anyone who wants to start working out but doesn’t feel confident about how to get started!

Meet your coach!


I’m Mathilda, a licensed personal trainer, nutrition advisor and the founder of fitnessbyrozenga.

My own fitness journey began in 2018, and since then, training, nutrition and health have become a big part of my life. What started as a personal interest quickly grew into a passion for helping others reach their goals.

After studying personal training and nutrition, I had a clear vision: to make training and nutrition simpler, more enjoyable and more sustainable for every individual.

Today, I’ve helped hundreds of women become stronger, build muscle, create better habits and, most importantly, feel more confident and comfortable in their bodies.

I don’t believe your entire life should have to revolve around a training plan. Your plan should fit into your life - not the other way around.
