(一)肌肉的對正：

Muscular Alignment: Muscles function most efficiently only when naturally aligned with their base and joint attachments. Natural aligned provides the most direct pull of the muscles that control your back, wrist, and finger joints.

肌肉運動只有在肌肉自然的與其關節對正時(不扭曲)，效率最佳， 自然的對正(Natural alignment)使得控制背部、手腕、手的肌肉得到最直接的收縮。

(二)關節Midrange伸展狀態：

Midrange function of Joints: Muscles function most efficiently only when the joints they control are operated within their midrange of movement. Midrange positioning and movement provides optimum leverage to the muscles involved.

肌肉運動只有在其所控制的關節在Midrange之間操作時效率最佳，Midrange位置與運動可提供肌肉伸縮最好的槓桿效果。

(三)一致的關節運動方向：

Uniform Direction of Joint Movement: Muscles function most efficiently only when three joints of a finger or the thumb are either flexed or extended together. In contrast to flexing one joint while extending another, simultaneous extension or flexion simplifies coordination of the muscles.

肌肉運動只有在手指的三個關節有一致的伸張或收縮時效率最佳，關節一致的伸張或收縮簡化了肌肉運動協調的問題。

(四)慣性的後續動作：

Follow-through: Muscles function most efficiently only when there is sufficient follow-through to avoid a build-up counterproductive tension. Sufficient follow-through means that, once a movement has been initiated, no intentional restraint is applied to the movement.

肌肉運動只有在手指有足夠的後續動作而避免累積反效果的肌肉緊張時效率最佳，足夠的後續動作意味當一運動開始後，不刻意制止此動作。
