Interval training is when you alternate between high-intensity exercise with low-intensity exercise. At lot of research has proven that interval training is better at burning calories than maintaining one pace through a cardio workout. I’ve read some articles that claim for best results you should alternate every 12 second, but I tried that and it’s virtually impossible. You can’t lose track of what you are doing for a moment, and you are constantly adjusting your pace. Your body really never gets the opportunity to settle in. It was a workout I’m not sure would be realistic for me. I find it’s much easier to interval train when you switch every minute or two.
But according a study at the University of New South Wales, intervals might be really worth trying, if you haven’t already. They found that women who did intervals for 20 minutes burned three times as much fat as women who worked out steadily for 40 minutes.
I’ve tried it, and it’s really difficult. You have to remain conscious of your pace continuously and cannot “get lost” in your audio book or daydreams.
