160 is also going to burn more fat because of the rate it leaves you body in

that rate is a faster and longer fat burning metabolism

so you can burn for 30min or for 1hour and 30 min with 30 min of more intense cardio

so you guys go for the first half hour at target heart rate and then increase it for the last half hour?
