It is better than nothing, but being on the treadmill does get monotonous after a few weeks. Really craving some outside (and WARMER) air! The sun did shine here today, and it was lovely, but I had to make a decision between the indoor treadmill and close to 0 F outdoors. Indoors, it was.
For me, one thing that makes the time spent on a treadmill worth it is the amount I effort I put into it. Strangely, the harder I work, the more bearable it is. I guess I'm too engaged in surviving to think about what I'm doing.
Spring is coming; it always does!
