Setback

It's July and I have had a major setback. I just don't feel like working out anymore. I know I should and that it makes me feel good but I am just not doing it anymore.  The setback is in my thinking. I don't have the motivation to go. I am still maintain my weight at 133 but I can feel my body getting squishier or not as toned. I just have one excuse after another. I know this is not the way I want to be or a way to get my goals accomplished, but still I don't go to the gym. It started when I was not able to go running anymore.  Now I am set on just not going at all. I hope this doesn't last too long and I can find my motivation again.
