[网盘]核心腹肌渐进系统健身课程
核心训练计划的设计必须既安全又合乎逻辑，以便在开始力量或力量运动之前建立坚实的基础。核心力量训练练习需要脊柱相对较大的运动范围，还需要整合所有肌肉运动类型（离心、同心和等长）。这些运动包括屈曲、伸展、侧屈、旋转以及这些运动的组合。培训师往往在这个阶段开始，在这个阶段停滞不前。下面给出一些常见的训练方法。(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.)
