It is quite an interesting and fresh look at the old problem. I think this book provides ways of building strength and accuracy that I would call this very foundation indeed. I'm rather a beginner. I will gradually familiarize myself with all exercises the book has to offer. One by one. I believe it is truly worth it.  

Do I recommend the book? Definitely yes!!

Due to Lars' method of arm and finger technique, my piano play has improved a lot. He goes into great depth and that gives me a lot of joy in playing the piano. 

 Amazing teacher!
