This is an educational method because Delavier explained by the good performance of gesture menu and impact of a particular anatomy of each movement. The practitioner not only runs stupidly movement without understanding the meaning, it supports to choose its own program based on its goals, its morphology, its free time. I tried for 8 months a famous method to body weight, not only have I not taken a gram of muscle but I lost! two months ago I'm the mass uptake Delavier ,, the results are already dramatic. I also feel much stronger nervously as other methods have exhausted me ... Congratulations to Frederic Delavier for this method which is for me the best (even better than the blue book) because the technique produces results supersets spectacular enough for beginners and for those with more experience.
