Personal Training in the Westerpark
Surrounded by the great atmosphere and nature of the parks of Amsterdam, I offer you customized training with a lot of attention.
Moving better
In my trainings I focus on a combination of mobility and strength, which will help you move better in your daily life. This helps to counteract the stiffness and poor posture of our modern way of living.
Personalized support
With a personalized program and personalized workouts, you will get the knowledge, structure, and motivation needed to get the most out of your fitness goals. Part of this program includes advice on lifestyle and nutrition, and assistance in implementing improvements in these areas.
Feeling healthy and free, outdoors in nature
Working out outside in the fresh open air is a very different experience than working out in the gym. You are exposed to fresh air and daylight, which improves mood, sleep, and the production of good hormones. These things combined will not only benefit your physical health but also your mental health.

Become stronger, more mobile, and more mentally resilient
Good, personal guidance can make a world of difference.
Knowledge: You finally know what you are doing and why, and you learn the correct technical execution of exercises.
Structure: You find out what you want, and what you need to do to get there, step by step. Because you follow a personalized schedule, you are never alone on your journey.
Motivation: You have someone who believes in you and will encourage you. I know you have the potential to achieve your goals, and I will support you 100% in that.
About me
Hello!
My name is Aris Spijker, and I am a born and raised Amsterdammer.
I was never much of an athlete as a child and teenager, but around the age of 20 I discovered my passion for sports: Calisthenics, the art ofbodyweight strength training.
After graduating as a historian, and spending five years managing in the hospitality industry, I decided to make my hobby, working out outdoors, my job.
Partly because of this, I developed broad interests in people and in the world.
In 2021, I founded my small business, Westerparkfit, out of my belief in all the beautiful aspects of working out outdoors. I felt that more people should experience those beautiful aspects.
In 2022, I began the Milo Performance & Education training program bythe Vondelgym to further deepen my knowledge and become an officially certified personal trainer.
In addition to my work, I have many interests and hobbies such as: traveling, music, philosophy, DJing, and getting out into nature.

Frequently Asked Questions
Mainly in Westerpark and Rembrandtpark. These are centrally located calisthenics training parks with many options and possibilities. In consultation, other places also may be possible.
Of course you can! With two or three the group is just small enough to be called personal training. With four or more, it takes the form of private small group training. For more information and associated rates, just contact me, and we'll discuss all the options.
Basically, we always work in blocks of 8 weeks with training schedules based on an intake in which goals, nutrition and lifestyle are discussed. This ensures commitment from both sides and also ensures the best results. Single training sessions are possible but have a higher rate as described above.
No, everything is possible, but discussing lesson schedules is always by mutual agreement.
The minimum is once a week. However, it is strongly recommended to train together twice a week in the beginning to make as much progress as possible and quickly learn a lot about movement and how your body works.
I have completed the Milo Personal Training course at the Vondelgym. This is a course affiliated with the European Register of Exercise Professionals (EREPS), the independent personal trainer registry in Europe.
