Hit your target heart rate and maintain it for about 30-45 mins or as long as you can.
its not just your opinion.........its the truth, speed and distance isn't as important as heart rate. find out what your max heart rate is, then i think the target heart rate is 70% of that.........i'd do at least 60 mins.....that is, if you have the time
Originally posted by 5.0Vert that won't be anywhere near as effective, you'll hit the target heart rate but you won't maintain it
Won't be near as effective? So by doing longer sessions of cardio at a lower pace you will be able to maintain your heart rate?
IMO, if your doing cardio it's either for fat loss or for a healthy liferstyle. Let's be real though, the vast majority of us do it for the fat loss. If anyone has done both kinds of cardio they will unanimously say that HIIT cardio is more effective that low-intensity at burning adipose tissue(fat).
Just an example for you......walk 50 yards and measure your heart rate, now sprint them same 50 yards and notice that not only your heart rate is much higher which obviously speeds up your metabolism but will stay with you longer.
I don't want to bore you to death anymore but here a few good reads on it.
