I am always absolutely amazed with major weight loss, especially when it's been done with diet and exercise (rather than surgery). Here is an amazing story of a man who has lost hundreds of pounds (literally) with the help of a good friend, a good diet, a little bit of exercise and a lot of motivation.
Please know that there are parts of the video that are a bit hard to watch, so if you're easily offended then I recommend not watching.
Now if that doesn't give you the extra motivation to head to the gym today, I don't know what does. Besides, it kind of makes those last ten pounds you're struggling with seem like less of a big deal, doesn't it?
