My muscles tense up and contract intensely. I try to keep this plank position as long as I can but it is much harder than it looks. It seems easy at first and I am optimistic, but soon I start to feel pain in my muscular shoulders, triceps, abs, and back muscles. I breathe hard and moan with fatigue. The vein on my forehead becomes swollen and my face turns red. My tense and tired muscles start to tremble and shake uncontrollably. I'm in pain. I try to go through it but time seems to stand still.
