Book 'The test factor'

For 25 years, I have been providing personal training to men of all ages. I find that many of them are intrinsically motivated to be the best they can be. Yet they fail to achieve their goals.

Sometimes they do many hours of cardio or put themselves on a very low-calorie ration to get rid of that pesky belly, which seems to get harder and harder with age. They often do not realise that this can break down precious muscle mass and unbalance their hormones, which prevents results.

A healthy hormone balance is crucial for optimal shape and health. And of course, for men, having enough of the primal hormone testosterone flowing through their veins is crucial.

Decline that many men experience with ageing they file under the heading 'old age', whereas in many cases it is about declining testosterone. Testosterone deficiency is occurring at an increasingly younger age in today's era due to increasing obesity, lack of exercise and too much chronic stress.

The good news is that you can do a lot about it yourself with core healthy diet, sophisticated exercise programmes and good stress management. As icing on the cake, there are also supplements and even hormonal therapies available to boost your testosterone.

An ideal handbook to restore balance and get everything out of your body and life. Thus, it can be used as a beginner, but certainly also as an ultra-fanatic.

The book de testofactor was co-written with Pim Christiaans, anti-ageing journalist, expert by experience and a (considerable) number of years older than me, making the book recognisable for men of all ages.

From our experience, we can tell you exactly WHAT you can do to balance your hormones, HOW it's because your hormones are out of balance, and more importantly: WHY you do get results with this book.
