Ask the Trainer: Cardio Intervals


Question: When walking outside or on a treadmill, does speeding up in short bursts increase the effectiveness? How? And is it all about switching up the pace, or are there other ways to get bursts in?

Answer: It doesn’t matter if you are walking or jogging or if you are indoors or outdoors. What really matters is the amount of calories you burn in a 24 hour period. If you take in less calories than you burn you will lose weight. The benefit of these short bursts is that your heart rate is increasing during the time you are walking faster and you are ultimately burning more calories. If you want to burn more calories I would include more bursts and do more interval training. Try doing 2 minutes of walking and rotate with 1 minute of jogging. You will burn more calories by doing this.
