using the fat burning mode on exercise machines at the gym actually isn’t the best way to burn fat. the key concepts to understand here are the percentage of calories that come from fat and total calories. the fat burning mode is typically set at lower exercise intensity where more calories burned come from fat. not as many calories burned during higher exercise intensity will come from fat. the point to understand though is that while more of the calories that you burn will come from fat at a lower exercise intensity you have the potential to burn more calories per session doing higher exercise intensity. the percentage of calories burned from fat will be lower during the higher exercise intensity but you will be burning more calories overall including the amount of calories from fat. also higher exercise intensity leads to a greater boost in metabolism even after you’re done exercising which burns additional calories. it’s best to do exercise that you’re comfortable with and that meets your level of training/conditioning. in general however increasing the time spent on exercise and increasing exercise intensity will provide a greater potential to burn more calories and lose weight.
what's the difference between the fat-burning mode and the cardio mode on the machines at the gym?
