When I was practicing pulling the rope, I felt a strong inner contraction in my stomach, thighs, shoulders, and neck. At the same time, my body felt heavy, just like the inner contraction when doing energy work. This feeling is also similar to the feeling of muscle tension. Will this cause muscle tension and affect obe? At this time, do I need to use my mind to relax the corresponding parts?
