While I have always said that I won't post before and after pictures and I am sticking to this, I have created a few for myself when I've worn an outfit that I had previously worn when I was bigger. These have let me point out the areas that have really changed and keep track of my progress.
Doing this has helped me keep focus at the gym as I can see what exercises have been working and reminded me that there is more to weight loss than numbers on a scale. It has also made sure I keep in mind that my body is still going through changes and will continue to do so for a while.
What I've found when losing weight is that because I spend every day in this body that I don't always notice the changes that other people do. This means that it can often take someone telling me that I look different for me to really see it, which is why I'm trying to make note of things that have changed now.
