So I've been able to stretch my treadmill walk to almost 20 minutes but for verity sake I'm trying to do something a bit different every other day. I realized that I was getting to that point of being competitive with myself and not focusing on building better habits. So yesterday instead of walking for ~20 minutes I took some time to stretch and do yoga like things for about 10-15 minutes. I was nice to do something different and returning to my usual treadmill work today. Tomorrow I plan to again spend sometime stretching but add a bit of weights to complement that.
