Exercise: You get out what you put in

Exercise is exercise is exercise, right? Well, not always. Although some is always better than none, it turns out that how hard you workout plays a big role in not only how much weight you lose, but how successful you are at keeping it off.

In a study that looked at two groups of people, one assigned to moderate activity and one assigned to intense activity, over a period of 18 months those that were assigned to the more intense exercise regimen lost the most weight and kept the most weight off in later follow-ups.

So if you can push it just a little harder, the case is pretty good that you should.
