I haven't done any research or anything yet. A good place to start seems to be just wearing the HRM for a variety of activities and recording the data. The Motoactv site will automatically do that. I believe it also allows you to mark whether you found a particular workout challenging or not.
I meant to wear it today when I lifted weights (CLX Burn Circuit 3) but forgot. That would be a really interesting comparison--cardio vs. weights. I was thinking about how instructors often say working large muscle groups gets your HR higher and now I can see whether that's true. And that makes me go back to the question of subjective vs. objective measures. Algorithms for calories burned aside, I would like to be able to compare various workouts and my objective vs. subjective assessments of them. Is CLX cardio REALLY hard? Or should I be doing something else?

Not sure if anyone's still following this thread, but I just had to post some of the data I've collected. All of these were using my Motoactv with heart rate strap.
CLX cardio 24 minutes Average HR: 135 Calories Burned: 234 CLX Burn Circuit 1 34 minutes Average HR: 114 Calories Burned: 254 Treadmill run 28 minutes, approximately 2.84 miles (manually entered mileage based on treadmill data) Average HR: 169 Calories Burned: 229 Breathless Body, 2 segments 11 minutes Average HR: 141 Calories Burned: 114 This makes no sense to me! I need to do some research on how this might be calculating calories burned. How could I possibly burn the most calories lifting weights? FWIW, the Motoactv does list specific activities, so each time I used the HRM, I told it what I was doing (aerobics, indoor run, weight training, etc.). This week, I'm going to try an elliptical workout and I'll do a run but not adjust the mileage. If anyone has any insight into these numbers, I'd love to hear it.

But you don't actually burn the most lifting weights according to your hrm, remember your durations are different... You burn more per minute with Breathless Body--if you did 33 minutes of it you would burn 342 calories compared with your 254 calories from 34 minutes of CLX Burn Circuit 1. Also, I am not sure whether you have noticed this, but often someones heart rate increases with duration of activity, I think I've heard it called drift. So a longer workout often has a higher heart rate towards the end, and if you follow one workout with another the second workout will often have a bit of a boost before you get started. So if you did these on different days with similar weather it is probably a fair comparison, but if some were add on's the add on might have a slightly inflated average heart rate and burn. |

I pulled a screenshot from each of these workouts from the Motoactv site. I put them into PDFs to be sure most people could open them and had to split the files to make them small enough. Anyway, you can see the HR graphs on them. On the site, you can roll over the lines to see exact numbers. The main thing I'm getting from these is that none of my workouts seem to be quite the interval-type I thought they were! Slysam, I'm totally enjoying all this info. Do you know of any websites I can learn more from? Ooo, I just found that the site can also tell me about zones. Do I need this info? What do I do with it?

*found it and more discussion on VF regarding calories burned, VO2 Max, aerobic base building: **Richard L.

Jeannine, I'm going to have to think about your notes in red for a while, especially the first set about the field test method. All I can think about exertion for step vs. bike is that you're using those large muscle groups to lift you, so maybe something about the way you're working those muscles makes you huff and puff?
I tried the calculator you linked to (non-VO2 version) and it gave me relatively close numbers. One thing I found really interesting was the information on net vs. gross calorie burn. That seems to explain why treadmills estimate high. Their calculator was a little lower (211 vs. 234) for calorie burn for my CLX cardio workout so I do kind of wonder if maybe my Motoactv is also showing gross calorie burn. I read through the info on calculating VO2 Max (walking, running, etc.). Might have to try that sometime when I can walk a mile by myself (without children, mail, etc.). I could easily use my Motoactv's GPS to mark out the distance, so at least that part would be accurate. I have yet to do that to compare the distances it gives me vs. the Fitbit. Oh, and when I did my outdoor run, it was REALLY dry here still. Would that mean I'd be less exhausted? Humidity is high now, around 60% (monsoon season) and temps are still 100+ so I haven't been outdoors much.

some sample exercise logs i've seen (for triathletes, for example) really track all kinds of factors like sleep, mood, etc. i know they're monitoring performance. i'm sure if i were more meticulous, i'd be able to pinpoint exactly when i had a good and productive exercise day.
