Next Year Olympic Dreams

Unintentionally, I was nailed to an athletic, sprinters Sunday afternoon. I had to do other irregular tasks. My gasolin won't work today.

Even if they run that fast, their pelvis is stable from side to side and up and down, and their core does not shake at all. How thick is the psoas major muscle (the large muscle that connects the upper and lower body) running inside their body? I was looking at the high-quality rubber-like gluteus maximus, iliopsoas, rectus femoris, hamstrings, and very fine standing upright of Tibia, etc. 

Just looking at the performance of the trained athletes seems to get luck good vibes I want to watch that captured by a high-performance camera.  slow motion, too.  Next year, the Olympics please do. I wanna see wonderful performances..!
