These days we are often told to exercise and meditate to keep ourselves healthy, but how often do we find there's no time. Our lives are too busy.
And that's why I'm recommending this little book. 8 exercises might not sound much and you could be forgiven for thinking it's simply hype and not worth a whole book. But in fact the 8 exercises together make a challenging routine that is completely different from anything else you might have tried, even yoga which is perhaps the closest thing I can think of is not really like this.
The author recommends introducing each exercise gradually, I followed this advice and have been learning a new postition each week, now on the fifth position. Some are difficult and take quite a bit of getting used to, so there is no point in hurrying. Adding each position slowly also means that you only need a little extra time each morning rather than getting up half an hour early to learn all the positions at once. In this way, the routine quickly becomes a habit much like cleaning your teeth - after a while it won't feel right if you don't do it.
Do the positions work? Definitely. Even I, as a beginner, feel a rush of heat and energy as I hold the positions, and these days I wake up far more alert and rested instead of stumbling about like a zombie. You do have to make a small committment of time and effort right at the beginning of your day, and you do have to try to do this every day to get the most benefit, but the results make it worthwhile. In time I can see this would help physical fitness, and it certainly creates a little calm before the busy day begins.
