Each week I get questions about cardio training exercises and how often we should do it. Many ask how hard they should work and why it’s needed in the first place. Some are confused about what exactly to do because there are conflicting opinons about how much cardio we really need.
The guidelines published by the American College of Sports Medicine suggest 30 minutes of moderate intensity exercise 5 days a week, or vigorous cardio 20 minutes a day, 3 days a week. For weight loss, you might need even more (up to 60-90 minutes) depending on your diet and other activities. It’s tough keeping all these rules straight and, the good news is that you don’t have to. Sometimes it’s best to forget the rules and get back to basics: Cardio isn’t just for weight loss.
