Hi Evie,
To reply to your question. The huffing and puffing which is the the perceived exertion is simply a unit measure of the effort you put in your workout. The calorie burnt is a combination of more factor than intensity put in
It depend on the length of the workout, type...
Example a 30 minutes weight lifting just by the nature result in less calorie expenditure, subject ive to the intensity compared to 30 minutes timed interval.
Just to add highly intense is the workout, high the perceived exertion is which is your heart rate.
Hope this reply your question
Yes, I think that's what Evie was asking, Cathe workouts, unless you do the same one over & over are not repetitive, where the cycling is. Maybe that's why it seems so much more intense. My workouts more or less correspond to higher perceived exertion = higher calorie burn, but not fat loss.
Lower intensity = lower calorie burn more fat loss.
That's okay nckfitheart2009, not everyone is going to get the same results, I have done higher intensity workouts, many of them, tempo runs are my favorite, and I'm really good at that (IIDSSM). I need to train the things though I'm not as good at too.
