Love the way the barre techniques are explained and modifications are also detailed in boxes. The Tuck (whether P57m Pvolve, or Pure Barre) is explained well so that a newbie can understand this favorite movement in barre classes.
So if you are taking or thinking about taking barre classes this book is a great read to understanding the core movements and getting tips on modifications while building strength to full movements and involving heavier weights in your barre classes.
