Now that we have established that exercises are important for weight loss, the question arises which exercise burns the most fat. There are two main types of exercises, cardiovascular exercises (lead to increases heart rate and metabolism) and strength training exercises (involve use of free weights or weight machines).
Our bodies burn fat best as we exercise at about 65-75% of the max heart rate for our age and sex. The only thing I could suggest would be to make sure the treadmill is going at a sufficient speed for you to achieve the right heart rate. You might like to consider other good exercises like eliptical trainers and the rowing machine for a bit of variety.
