Stay young, reduce injuries and improve sport performance with MAT – Muscle Activation Techniques™
MAT™ is a powerful muscular assessment tool that analyses and corrects muscular imbalances in the human body. Through a unique systematic format MAT™  techniques are used to “jump start” the muscles in order for the muscular system to function with maximum efficiency.

MAT™ also helps to prevent muscle loss, one of the signs of ageing! As we age, the load our muscles can take diminishes and consequently more muscles inhibit. Because MAT ensures that each muscle is receiving a signal to contract, when you exercise with load on the MAT™ training programme, your body will now have the ability to maintain or gain muscle mass, thus reducing or eliminating sarcopenia/muscle loss associated with ageing.

MAT™ Personal Training starts with a MAT™ screening. More than 300 muscle tests can be used to assess which muscles or specific muscle fibres are inhibited or weak. Both people doing general exercise for fitness and amateur athletes benefit from a MAT™ screening.
Compensation as a result of muscle weakness leads to faulty movement patterns. If you do not adapt your training programme you will be strengthening the body in the wrong position, strong muscles will get stronger whilst weak muscles will remain weak.

By ensuring your muscular system is working optimally Judith will be able to reduce the risk of injuries, improve recovery times and performance: speed, power, strength and agility. Judith will develop a programme that aims to achieve not only your personal goals but also improve muscle function by activating inhibited or weak muscles through MAT™ treatments and  specific MAT™ exercises. For more info about a MAT treatment see MAT™  rehab.

So what does this mean for you?

• You will stay younger by preventing muscles loss associated with ageing!
• You will not only feel fitter and more in shape, but you will also get better results in difficult to train areas like abdominals, hips and back.
• A more targeted approach to reduce aches, pains and injuries.
• You will be able to improve your sport performance. In the US, where MAT™ was developed by Greg Roskopf 25 years ago, many professional sport teams and athletes use MAT™ to improve performance.



  • I train for two and a half years at PT Plus with Judith. Judith is excited, full of energy and motivates me very much! I had a lot of pain in my back, but by the good targeted sports sessions I now know better how I should use my back. In addition, I have much less back pain. I feel fit and in shape!

  • When I first came to PT Plus, I thought that I was coming to a normal Personal Trainer. My objective was to improve my level of fitness. I had unsuccessfully been trying to eliminate certain discomforts (stiff neck, back pain) which had developed, and wanted to improve my fitness in spite of these problems.

Knowledge of the muscular system

More than 300 muscle tests can be used to assess which muscles or specific muscle fibres are inhibited or weak.

MAT™ treatment will restore the communication of the Central Nervous System (CNS) with the muscles and improve the ability of the muscles to contract.
The treatment is followed by MAT™ exercises to strengthen and reinforce.

MAT™ reduces pain and discomfort from chronic injuries, resolves sport injuries, improves athletic performance and keeps you young!

PT Plus Muscle Activation Techniques

The only specialist centre in the Netherlands. Muscle Activation Techniques™ is a revolutionary approach to assess and correct muscular imbalances within the human body. Overload, stress, injury and ageing causes muscles to become inhibited or weak. MAT™  restores contractile efficiency of the muscular system, ensuring it can function with maximum efficiency. MAT™ helps people of all ages to reduce injuries, improve sport performance and maintain health and youth.
