That moment at 3am when I realized I was using my whole body wrong on the treadmill
I have been running on treadmills for like 15 years, on and off. Last Tuesday, at a cheap gym in a strip mall, I was huffing through mile 2 and my lower back was screaming. I always thought that was just part of running, you know, tough it out. Then an older lady got on the machine next to me and she was practically floating. I watched her for a few minutes and noticed she wasn't leaning forward and grabbing the handles like me. Her arms were swinging from her shoulders, not her elbows, and her core looked solid, not hunched. It hit me like a brick: I had been fighting the machine with tension, not letting my legs do the work. Next time, I slowed way down and tried copying her posture, and my back pain dropped about 70 percent. Has anyone else gone years doing a basic thing wrong and only figured it out by watching a stranger?
