Our independent entrepreneurial personal trainers

Joël van Wijk

Welcome to Personal Performance Training.

My name is Joël van Wijk, founder and owner of Personal Performance Training in The Hague. Since 2010, I have been guiding clients at the highest level in achieving their physical and mental goals. With years of experience, discipline, and a strong focus on quality, personal attention is central to my approach.

My background consists of various recognized training courses and specializations, including Fitness Trainer A & B, Personal Trainer, Nutrition and Health, Orthomolecular studies, Kickboxing Trainer (SKMO level 4), Functional Training, Conditioning Training, Rehabilitation Trainer, and Sports Fasting. This broad and in-depth knowledge enables me to deliver top-level customized solutions.

At Personal Performance Training, I work exclusively with a personal and results-oriented approach. No standard schedules, but fully tailored to your body, lifestyle, and goals through extensive testing. Through this method, we create sustainable results together, both physically and mentally.

You can come to me for, among other things:

• Weight reduction and body recomposition
• Building strength, fitness, and performance
• Mental resilience and coaching
• High-quality, personal guidance in a professional and discreet setting

Continuous development is a natural part of the profession for me. I continuously invest in new knowledge and methodologies to always offer my clients the best possible guidance.

The training methodology is a well-thought-out combination of strength training, cardio, functional training, core and stability training, supplemented with elements from kickboxing. This ensures an effective, challenging, and varied high-level workout.

“Do you finally want to lose those excess kilos and face life full of energy again?

As a personal trainer, I ensure that your body and mind become truly stronger. We build your muscles and burn fat, while increasing your resilience. Sometimes your body holds you back due to a medical limitation. For example, a back or neck injury that just won't go away. With my background as a Medical Fitness Trainer, I can train you safely. No standard schedules, but tailored to your physical situation. My qualifications (a) Personal Trainer and (b) Medical Fitness Trainer were obtained at FysioPhysics in IJsselstein.”

Ishaan Rambaran

Ishaan Rambaran is an independent entrepreneur and professional.

Martial arts have been my passion from a young age. I started with taekwondo and earned my 1st dan (black belt) before transitioning to kickboxing. Today, I am a professional kickboxer, competing at a high level.

I bring this competitive mindset into my training sessions, focusing on strength, endurance, technique, and mental resilience.

Remy Tonino

Remy Tonino is an independent, entrepreneurial professional.

Nice to meet you, my name is Remy Tonino. I am 42 years old and have been a dedicated strength athlete for 22 years. For me, strength training is not just a sport, but a lifestyle that permeates all aspects of daily life.

Like many others, I once started without a clear plan: unstructured training, nutrition without direction, and little visible result. That phase motivated me to seriously delve into the field and pursue a career as a personal trainer in the fitness industry. With that knowledge and practical experience, I now help others to train purposefully and effectively.

As a personal trainer, I focus on teaching a strong foundation in strength training. My goal is to make you not only physically stronger but also mentally more resilient. I strongly believe in the synergy between body and mind: as you grow physically, your mindset grows automatically with you.

My mission is to guide driven people toward a stronger, fitter, and healthier body – with a sustainable approach that delivers results. My background and certifications:

• ACSM Health and Fitness Instructor
• Fitness Trainer A/B (AALO)
• Certified Group Fitness Instructor (AALO)
• CPR and First Aid certificates

Everyone knows the saying: “You are only as strong as your weakest link.”

If that is your physical condition, then it is time to work on it together.
