The guidance

90 Days you will be guided in your exercise, nutrition (recipes etc.) & mind, relaxation and breathing techniques. You will get access to various workshops and seminars, daily (app) contact, eating and exercise schedules, and more!


Everyone in society wants to change something in his or her life, often we fall into old habits and patterns! everyone wants to, but the motivation, perseverance and willpower is often lacking so we continue on the old footing.
It takes 21 days to learn a new habit and 90 days to turn it into a lifestyle.

When your body and mind are reprogrammed for 90 days, the new programs become an automatism and then your new lifestyle is a fact! but try to maintain this on your own for 90 days 100%. in this trajectory we will help you completely so that you will be able to go through life easier on your own. together we will break through the old patterns and create new ones so that you can develop the life you want!

Emotional addiction

Laziness, stress, listlessness, low energy, unmotivated, tension, pressure in your head. All these emotions see your body as a chemical imbalance that you can become addicted to just like alcohol, cigarettes etc. This means that your body is used to a certain habit and if you want to change something your body tries to sabotage it in order to keep the same old emotions, feelings, this is why change is so difficult, because your body is emotionally addicted to the habits (chemical imbalance) in the body. During our free workshop we will explain this in more depth so that you understand why it is so difficult to make change in your life and during the 21/90 we will teach you how you can break this and learn new healthy habits.

Dopamine addiction

In addition, your body and brain are addicted to fast dopamine such as chocolate, carbohydrates, Netflix, social media, masturbation, shopping, chilling, etc...These are all things that give you a quick fix. This will make you addicted to this and in the short term it will take us further away from our goals. When the body and brain are satisfied with this, there is no more energy for tasks that are less likely to give dopamine. These are precisely the tasks that give long lasting results. So we will have to restore the dopamine intake to a more healthy balance.

Message from one of our teachers

We wait for crisis, trauma, loss, disease and tragedy before we get down to looking at who we are, what we are doing, how we are living, what we are feeling, and what we believe or know, in order to embrace true change. Often it takes a worst-case scenario for us to begin making changes that support our health, relationships, career, family and future...

My message is: Why wait?

We can learn and change in a state of pain and suffering, or we can evolve in a state of joy and inspiration. Most embrace the former. To go with the latter, we just have to make up our minds that change will probably entail a bit of discomfort, some inconvenience, a break from a predictable routine, and a period of not knowing. The unknown is where all the magic is hero! Let's change as a choice, instead of as a reaction.
You can learn change in a state of pain and suffering, or you can learn change in a state of joy and inspiration.
The choice is yours

Negativity, stress, tensions no longer exist for me thanks to the master class

Gil is a great yoga teacher: he immediately notices if you have trouble with a pose and then helps (with props and instructions/adjustments) until the pose feels comfortable for you. Very nice combination of yang (challenging) and closing yin (total relaxation).
