Certifications & Credentials

WHAT SEEMS IMPOSSIBLE TODAY, WILL SOON BECOME YOUR WARM-UP

Meet the Trainer

My mission is

...to support individuals in reaching their optimum fitness level and becoming fitter, faster and stronger. Holding an MSc in Organisational Psychology and experienced in football, tennis, and martial arts, I have a good understanding of the mind-body connection in wellness. I aim to foster this connection in others for their well-being.

I became a trainer

...because I wanted to share my passion for sports & fitness and help others achieve an optimal level of fitness so they can perform any activity without any effort and with maximum enjoyment.

My specialty

Is using different types of training such as resistance training, speed-agility and quickness, plyometric training, balance and core activation exercises programmed in a phased approach and tailored to anyone's goals and requirements in order to achieve optimal and sustainable results.

How I stay fit

I do functional-training with a power-phase focus 2-3 times a week, still play amateur level football and tennis and once or twice a year, prepare and participate in an athletic competition, such as Mudmasters, Spartan Race, Dam-to-Dam (biking or running).

Why OPTIFIT PERFORM?

Evidence-based programming

Sweat Smarter, Not Harder!

I design workout programs based on the latest scientific research of the NASM OPT model and ensure that every exercise and training technique is backed by evidence. This approach maximises the effectiveness of your workouts, helping you achieve optimal results while minimising the risk of injury.
Personalised Training Approach

Your Fitness, Your Way

I do not sell standardised 12-week programs to become your best self. I will tailor your training program specifically to your goals, fitness level, and any specific needs or limitations you may have with re-adjustments to the program based on progress and enjoyment.
Scheduling Flexibility

Fit Your Fitness into Your Life

Life can be hectic, which is why I offer flexible scheduling options to accommodate your busy lifestyle. Whether you prefer early morning sessions, late evening workouts, or specific days of the week, I strive to find a schedule that works best for you, ensuring you can consistently prioritize your fitness.
Accountability & Motivation

Stay on Track, Achieve More

I believe in the power of accountability and motivation to keep you on track. I provide ongoing support, encouragement, and feedback throughout your fitness journey, holding you accountable to your goals. By keeping you motivated, I help you overcome obstacles, stay consistent, and maintain a positive mindset to achieve sustainable results.

Step by step evidence-based approach

01

COMPREHENSIVE ASSESSMENTS

This phase uses validated tools to measure your current fitness status, analyzing factors like body composition, cardiovascular fitness, strength, and flexibility, as well as understanding your story, health history, and aspirations, delving into the intricacies of what makes you, you.
02

EVIDENCE-BASED PROGRAM DESIGN

The evidence-based approach to program design is based on the National Academy of Sports Medicine (NASM) OPT Model. We will create a weekly, monthly and yearly program, as well as adapt it based on progress and enjoyment.
03

CONTINUOUS PROGRESS MONITORING

Tracking progress is essential for achieving your fitness goals. This involves weekly & monthly re-assessments, as well as using data provided from fitness trackers and apps.
04

REVIEW, ADAPT & IMPROVE

We will use the monthly assessments to improve the program, perform any necessary adjustments with the overall goal to increase likelihood of achieving your goals, but also increase the level of enjoyment in the program.

Frequently asked questions

Please reach out through our Live Chat if you have other burning questions that are not already covered in the FAQ.
What is your cancellation and refund policy?
The cancellation policy requires a 24-hour notice for all sessions. Refunds are an option within this timeframe. If not refunding, consider rescheduling the session for the next 48 hours. Cancellations within less than 24 hours result in the full session price being charged.
How do I pay for the sessions?
According to the price table above and you can find more details in the "Terms of Service", invoices are provided on a monthly basis, depending on how many sessions we will have per month. For 4 sessions a month, I will send an invoice for those 4 sessions corresponding with the price per session from the price table above (i.e. in this case 4*65e = 224). For 10 sessions a month, the price per session goes down to 55e per session, therefore price per month will be 10*55e = 550e.
Do you also offer pre-paid multiple session packages?
Yes, packages of 10, 12 or 25 sessions are also available. They can be paid upfront and can be discussed during the initial session. Conditions regarding scheduling and payment will be the same as with the monthly pricing options.
What is evidence-based personal training?
Evidence-based personal training means that firstly, my training is based on the latest scientific research and secondly that observation and evidence are key factors in every step of the training process: assessments, programming and monitoring progress.
Do you offer nutritional guidance as part of your services?
Absolutely! I believe that nutrition plays a vital role in achieving fitness goals. I will provide basic nutritional guidance and offer suggestions to support your training program.
