This blog is one way to keep an eye on progress and to remind myself of my goals but I will also be using my phone and a couple of free apps.
To monitor my calorie intake I'll be using "myfitnesspal" which has an app for android and iphone. I've tried it before and it works really well. It seems to have more foods in than the apps you pay for because of user generated content.
And to record at least some of my exercise I'll use "endomondo" which is also free and has an app that uses your phone's GPS to record your exercise, no good for the gym but cool for running/cycling and walking.
