Hello. While doing cardio what should your heart rate be at to burn fat? Also what is a good length of time for cardio?? Thanks...

first you find max HR (220-age=MaxHR) and then you take that # and muliply by .6 and .8, to find your lower and upper range, respectively. Duration - start at 20min and work up to 60 min. If you can split it over two sessions that's better. I start and end my workouts with cardio.
