"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?
yes
what happens to muscle if you just jog for extended periods? what places do you lose it from?
