(A core training program must be designed both safely and logically in order to build a solid foundation before beginning strength or power exercises. Core strength training exercises require a relatively large range of motion in the spine and also require the integration of all muscle movement types (eccentric, concentric, and isometric). These movements include flexion, extension, lateral flexion, rotation, and combinations of these. Trainers tend to start at this stage and stagnate at this stage. Some common training methods are given below.)
