"The way to jog to preserve muscle and increase your fat burning rate is to do intervals.

What you do is run fast for 10-15 seconds. Then you slow down to either a walk or a very slow jog for 20-30 seconds. And you keep repeating that sequence over and over for about 20 minutes. This is ideal for burning fat and maintaining muscle.

Try to avoid jogging/running for over 20 minutes if you want to preserve muscle."

Is this true?
