I've been working out for several years, but in the last 7 months I've changed my workouts to be focused on lifting instead of cardio (and more focused on free weights and heavier weight goals). I always did a full body workout with cardio, it was just more machine based and I wasn't challenging myself... just going through the motions. A few months ago I went through a serious break-up and working out became my anger management and my sleeping pill. So, I started going to the gym 4-5x per week instead of 2-3. I decreased cardio and increased lifting. Now I love it! It's no longer anger managment or a sleeping pill, but just fun. I look better than I ever have. That's my motivation... looking great and feeling good. Tension headaches that were frequent are rare now. I also started keeping a journal, which has helped a lot!
