I’ve personally found that honestly speaking, the best workout you can find is on the elliptical.  Yes, the elliptical machine that can be found in your gym is an incredible way to burn off fat and calories.  Basically speaking, it is a whole body workout that if you do it right, includes the arms, legs, core, everything really.  Even the butt.  Now if you want to define your butt, you should also use things like squats to enhance the muscle among other things.  But this being said, basically speaking when you run, you are working the legs for the most part, and of course you get the core in the process. 

But with the elliptical, even though it sometimes seems like you are exerting less effort, you are exerting more, it is just balanced throughout the whole body instead of just in one area.  So it feels like less, which is great for endurance purposes.  I have personally been able to go longer on the elliptical and subsequently see much greater results.  So it’s definitely a fat burning method I would highly recommend, at least if you actually want to burn fat and lose weight.  Otherwise, well you might want to choose something else, or for that matter not exercise.  But exercise of course is also important for the heart, so it’s definitely not something to realistically ever drop.
