How Much Time To Spend On Cardio

How Much Time To Spend On Cardio You're in a hurry to get in a workout because you're committed to a weight loss goal, but don't have half an hour to jog on the treadmill. No problem! According to research reported in the International Journal of Sport Nutrition and Exercise Metabolism just 2 minutes of sprint interval exercise provides you with the all day fat-burning potential of a 30-minute steady state run.

Subjects ran 3 times a week for 6 weeks, either sprinting in intervals for 2 minutes or running at the same low to moderate intensity jog for 30 minutes. Even though maximal oxygen consumption was 150% higher for the steady state runners, and they had a higher average heart rate during exercise, the intensity of sprint interval training elevated 24-hour oxygen consumption at a rate similar to what was achieved with 30 minutes of treadmill running.

True Strength Moment: It's great to know that you can close the gap on workout effectiveness by ramping up the intensity if you're in a hurry. But when you have the time, there's nothing wrong with putting in the full half hour. Changing up a stale cardio routine could be just as beneficial as planning out a new phase of weight training.
