절정 수축, 이게 되면 등이 달라집니다 [황철순의 노하우 압수수색 EP.5]

How to Build Three-Dimensional Upper Back Taught by Hwang Chul-soon | Back Workout Know-How Search & Seizure EP.5 If your upper back feels flat despite working out hard, it is highly likely that the depth of contraction was insufficient. We have discovered the method to perfect three-dimensional upper back by completely isolating the trapezius, infraspinatus, and teres minor muscles, rather than simply pulling. [Key Lesson Points] ▸ Principle of Peak Contraction: You must pull all the way to the end and hold to create patterns and shadows on the upper back. ▸ Elbow Angle: Slightly lower than shoulder; pulling upward stimulates the teres minor and infraspinatus muscles. ▸ Upper Back Outer Isolation Method: Pushing the elbows outward makes the small patterns more distinct. ▸ Cable Alternative: Even without a machine, you can achieve the same stimulation by removing your thumb and pulling with your little and ring fingers.
