Missed One

Walked Sunday, Monday, and Wednesday, but missed my walk/run on Tuesday because of work. Today I went 4 miles on the usual walk/run route and it went okay. My knees and right hip felt...not strong. I think I need to do some strengthening exercises. The somewhat faster pace seemed to help like it did last week. For whatever reason it works out the kinks quicker, but I also feel like it's not sustainable. I also thought more of my posture. Shoulders back, more upright, use the glutes, etc. If I can do this a little more I think it will pay off.
