Ms. Daniels explains how everyday misuse of our muscles can and usually does cause pain later on in life and how to slowly try to correct it. She uses client examples of how a client comes in with certain pains, discusses their daily life (i.e. how much time they are sitting in front of the computer), and then helps them go through exercises to help ease the pain and help bring their bodies back to their natural position.

Straighter, Stronger, Leaner, Longer provides clear pictures on how to do the stretching exercises that Ms. Daniels recommends. The pictures are divided into the sections where certain muscle groups are discussed.
