    Did you know that if everyone would stop exercising, health would actually improve?! And even dramatically?! Yes, this is what health statistics teach us.

    Because, being healthy means being without injury. Ever since people started exercising for health, ironically injuries have increased significantly. Bone fractures, torn muscles, you name it. Indeed, our overall cardiovascular health has gotten better, but most forms of exercise mainly result in wear and tear of the body – which obviously decreases functional abilities in time.

    So, now what. Don’t exercise?

    No, you should definitely exercise for your health, but inform yourself properly!

    Let’s start with the basic idea of correct exercise – in my opinion, the definition of correct exercise. Correct exercise is: resistance training, specifically designed for a particular individual with the goal to effectively, efficiently and safely stimulate improvements in functional ability (strength, conditioning, flexibility, etc.), while the chances of acute injury and wear and tear are being minimized.

    The best exercise for health

    The method that underscores and follows this basic idea (and my definition of correct exercise) best, is High Intensity Training (HIT).

    (Be aware, however, that this is something completely different from the popular method called High Intensity Interval Training (HIIT)! (In case you’re interested, you can read more about this difference in my blog ‘What is High Intensity?’, through this link: https://joeri.app/what-is-high-intensity-training/))

    High Intensity Training (HIT) is designed to be utterly effective, time efficient and safe. And it is in its very essence different from most other training forms.

    Exercise methods like HIIT, CrossFit and most forms of cardio exercises are so called high impact activitities. Also, these kind of exercises are meant to be performed in an explosive and ballistic fashion. The downside of these methods, is that they take a toll on your joints and increase chances of acute injuries.

    High Intensity Training on the other hand, is nothing like that. There is no acute wrecking yourself or undermining the long term health of your joints. Yet, the fact that it is a very safe method, does not automatically intail that you have to give up on benefits. The opposite is actually true.

    Some of the important health benefits that High Intensity Training has to offer, are:

    • increase of muscle strength and size [1]
    • improvement ofconditioning [2]
    • increase of basal metabolic rate [3]
    • increase of bone density [4]
    • increase of insuline sensitivity (contributes to a more stable blood sugar) [5]
    • improvement of flexibility [6]
    • decrease of blood pressure [7]
    • reduces pain for people with arthritis [8]
    • can lead to less pain in the lower back [9]

    Want to get started right away? We’re offering you our HIT Guide E-Book for free. Click here to receive the HIT Guide in your mailbox!

    Furthermore, we have designed an app, Joeri HIT, to assist you in maximizing your workouts. It is ultimately designed for both individuals and personal trainers.

    Where can I find the app?

    You can find Joeri HIT, the High Intensity Training app for trainees and trainers, in Google Play Store and Apple App Store.


    We got two High Intensity Training apps

    1. Pro app i.e. Joeri pro (for trainers and other professionals who use HIT)

    2. Personal app i.e. Joeri HIT (for individuals who want to keep track and analyze their own results from HIT workouts).
