Query: Difficult and time consuming, not for beginners.

I was interested in a work out that would lengthen muscles as The Method boasts of. However, I found many of the excercises difficult to complete, and straining the neck.The entire tape focusses on the lower body abs, thighs, and back side. The first part of the tape is 15 minutes, focussing mostly on abs. The second part is 30 minutes which begins with a repeat of the first ssection, then goes on to a focuss on the legs. I feel 45 minutes is a lot of time invested in toning without working out the upper body.I do enjoy the leg work out and have used parts of the ab and the entire leg work out in my usual toning routine.
