Nathan has been great. As an online trainer, I think he strikes a great balance of putting the onus of responsibility on you as the client while also individualizing a diet and training that best suits your lifestyle and goals.

He is extremely responsive to questions and with feedback. I started out as a complete beginner to weightlifting and he has made me feel comfortable and safe along the way by providing regular feedback of my form.

I can’t believe how much progress I’ve been able to make in terms of my strength and physique. I wish I had found him and this service years ago!!

Strength Program

I’ve been working with Nathan for ~7 weeks, and it has been overwhelmingly positive, & one of the best online personal trainers.

Nathan responds to messages within a few hours. I can honestly say that the workouts are the hardest I’ve ever done. I came from doing all 3 P90X programs, and really liked the cardio/plyo exercises. Nathan let me continue to use those, in combination with regular training.

The app is also really easy to use, great for tracking everything. Additionally, the meal plan was constantly varied, so I never got bored with foods. I often had to make adjustments to make the macro’s work with foods I had available, but nothing too bad. Highly recommend Demetz for the whole package – nutrition and training.

What Working With a Personal Trainer Is Like

Working with a certified personal trainer is a step in the right direction for better health, a better attitude, and greater overall fitness.

But what does this working relationship look like?

Initial consult

Our journey together commences with a crucial initial consultation, a pivotal moment where we delve into your aspirations, preferences, and aspirations, forging the foundation of our collaborative endeavor. During this meeting, we will discuss your fitness goals, aspirations, and dreams, allowing us to get to know each other on a deeper level.

This is your golden opportunity to familiarize yourself with your personal trainer, assessing if they align with your unique needs and expectations. You can freely inquire about their approach, experience, and training philosophy to ensure it resonates with your vision for this transformative journey.

Simultaneously, this consultation allows me to gain invaluable insights into your persona, your fitness objectives, and the unique perspectives that drive you. By understanding your goals and expectations, I can tailor an approach that caters precisely to your needs and aspirations, ensuring our working relationship is based on mutual understanding and shared purpose.

My mission as a personal trainer is to create an environment where you feel supported, motivated, and empowered to pursue your goals with unwavering determination.

What Working With a Personal Trainer Is Like
Goal Setting

Goal setting.

With introductions out of the way, we’ll be ready to start setting more formal goals for your fitness journey.

Are you trying to lose 20 pounds in the next few months? Are you training for a marathon next year?

Are you just trying to eat healthier?

Whatever you’re hoping to achieve, it’s my job as your certified personal trainer and coach to make sure your goals are realistic, achievable, yet challenging enough to motivate you.

Nutritional planning.

The world of nutrition is overwhelming and confusing for most people who aren’t already familiar with it.

Everyone has different nutritional needs & nutritional advice, and it’s important to think about nutrition in many different ways; the calories you eat, the balance of macronutrients that you eat, and the micronutrients you get on a daily basis can all influence your mood, your health, and your athletic performance.

Don’t worry. as your personal trainer I’ll take the guesswork out of this experience so you know exactly what you should be eating at all times (nutrition advice).

Whether you are gluten free, just want to improve healthy habits in eating, or need a simple to follow nutrition plan my nutrition coaching and training plans are right for you.

Workout Planning

Workout planning.

Any exercise is better than no exercise, but at the same time, some exercises are better than others.

As your personal fitness coach, I’ll work with you directly to design and help you create workouts/execute workouts that are fine-tuned to help you achieve your goals.

Whether you’re trying to become an Olympic record-holding weightlifter or you’re just trying to extend your lifespan with strength training and cardio, I will design the perfect & effective workout schedule for you on your own time.

The workouts I create are appropriate for your fitness level and your situation. Body weight only, resistance bands, full gym access, free weights at home: whatever you have access to is sufficient for the workouts I create.

Setting Your Personal Fitness Goals

What are you hoping to get out of your online personal trainer?
These are some of the most common personal fitness desires I’ve helped people achieve:

Lose weight.

Weight loss goals can stem from various motivations, each holding significant importance to the individual embarking on this transformative journey.

For some, the driving force is to enhance their overall health and reduce vulnerability to certain health complications, ultimately extending their lifespan. Shedding excess weight can lead to improved cardiovascular health, reduced risk of diabetes, and alleviate strain on joints, among many other health benefits.

Others find motivation in the desire to fit back into the clothes they’ve always loved, rekindling confidence and a sense of empowerment as they embrace their desired physique once again.

Moreover, countless individuals simply aspire to look and feel better, seeking the satisfaction of increased self-esteem and a positive body image.

Whatever your case may be, rest assured that I am dedicated to helping you achieve your weight loss goals. Through personalized strategies, tailored workouts, and customized nutritional plans, we’ll work hand in hand to create an effective and sustainable approach.

Your journey is unique, and I recognize the individuality of your aspirations and challenges. Together, we’ll navigate this path, overcome obstacles, and celebrate each milestone reached.

Embark on this transformative voyage, and I’ll be your unwavering supporter, empowering you to reach your full potential and embrace a healthier, happier, and more vibrant life. Let’s make your weight loss aspirations a reality, one step at a time!

More aesthetically muscular?

Whether you’re training to become a professional bodybuilder, or you just want to carry yourself with more confidence, as your online personal trainer I can help you build more muscle.

Improve athletic performance.

I’m also here to help you improve your athletic performance, if that is your desire.

Running faster, lifting more, and becoming more agile don’t happen naturally; an online personal trainer can make these feats much easier to achieve.

I have clients who are simultaneously able to run a half-marathons at a per-mile pace in the 6s while also have the ability to squat and deadlift 500+ pounds each. Add to this that these clients walk around at lean body fat, and you have an athlete in front of you.


I can do the same for you, and indeed have done the same for many men and women, as well as myself.


Improve athletic performance
Prepare for a marathon event

Prepare for an event.

You may also use an online personal trainer to help prepare for a specific event, like an upcoming half marathon, powerlifting competition, or other event.

I have coached clients to triathlons, run competitions of various lengths, push-pull powerlifting events and more.

My combination of certifications in areas such as running, strength training, fitness nutrition, and others areas, combined with my experience coaching 350+ clients provides with the necessary skills to help you prepare for virtually any event.


Feel better.

And of course, some people pursue personal fitness just because they want to feel better, inside and out.

Feeling better is a multifaceted concept that extends beyond just physical well-being. It encompasses various aspects of one’s life and overall health. Let’s delve deeper into the different dimensions of feeling better and how personal fitness plays a crucial role in achieving this goal.

Personal fitness serves as a powerful tool in achieving this objective, promoting overall health, self-confidence, emotional balance, social connections, and a positive outlook on life. Incorporating regular physical activity and a balanced diet into one’s lifestyle can lead to a happier, healthier, and more fulfilling life journey.

Simply put, improve physical fitness can help improve your overall life mentally and physically, enabling to better enjoy for yourself and with family and friends.
