"Best" can be a subjective word but for me, the best cardio machine to burn fat would be a treadclimber. There are several cardio machines like treadmills, stairclimbers and elliptical trainers but a treadclimber can combine the movements of all three. The word "TreadClimber" is actually a combination of treadmill and stairclimber so you get both the running/brisk walking and climbing benefits while enjoying the low-impact motion effect of working on an elliptical trainer. All these are made possible thanks to its two "dual treadles" and its handles which aid in keeping your posture upright and maintaining your balance. In my opinion, a treadclimber is the best cardio machine to burn fat for several reasons:

(1) A treadclimber gives you 3 workouts in 1. By using a combo of varying exercise motions in a single movement, you'll get triple benefits and this can definitely accelerate the fat-burning process. The workout can become more intense as the duration increases.

(2) A treadclimber doesn't put as much stress on your joints as a treadmill does. Your goal is to burn fat and enjoy your workout not putting your joints at risk.

(3) A treadclimber is less boring as compared to the other cardio machines. Boredom can affect your workout and dampen your motivation and enthusiasm.

The best way to get the most out of a treadclimber is by using the following training method. You can incorporate high-intensity interval training, that is doing short bursts of intense cardio sessions highly effective for burning fat fast, then low-intensity sessions to rest a bit then repeat with high-intensity and so on. So that will be fast-paced, slow-paced, fast-paced etc… Doing this several times will ensure optimum fat loss. It's also a great way to avoid boredom which can happen when sticking with a single pace. Some people can also do fast-paced, rest totally for 1-2 minutes without cooling down too much then start another fast-paced session. This works equally well.

There are many treadclimbers on the market but one which I've found to be pretty impressive is the versatile Bowflex TreadClimber TC20, Bowflex best cardio machine ever. The TC20 was chosen as the best premium treadmill in About.com Readers' Choice Awards. People are reaping amazing fat-burning benefits by using the TC20.
