I found myself looking forward to the hour where all the voices in my head went silent and I could just count reps, listen to myself breathe, and dig into the physical effort of exerting myself to the edge of my ability. Then seeing those edges expand further than I thought possible.
This touches on two of the big reasons, maybe the biggest reasons why I exercise too. It allows me to step out of my life for a bit and focus on moving in whatever form the exercise takes that day. As well, I like the idea that it allows me to push a little and I like that.
