When out jogging my heart rate was 170?

Question:

...do you think thats good? was it beating fast enough to burn fat? oh and based on my weight of 135 pounds and 5'8 in height, how many calories would i burn in half an hour? thanks!!

Answers:
Your maximum heart rate is 220 minus your age.
The fat burning zone is 80% of this number.
Most people burn about 100 calories per mile depending on their speed.

Depends on how fast you run. You burn about 100 calories a mile.

actually Im pretty sure thats too fast. You need to slow it down in order to burn fat. If it goes too high your just burning muscle. I am in a workout program that teaches all that stuff. So I know Im not wrong. It should be about 140...maybe 150 NO HIGHER its not safe for you and your losing muscle not fat
