Which is better? Cardo question

mcneelymama

I do excercise tv workouts. Which is better? One 20-30 min cardio workouts or two 15 min cardio workouts spread out through the day?

30 minutes is better than 20 minutes but you need to get your heart rate up to get to the fat burning mode. if you are warming up and cooling down for 10 of the 20 minutes than 30 minutes might be better.
