Yeah, it's definitely tough with intervals especially when they deviate from the exercises Spark has in the tracker (like Nicole's jump rope intervals). Personally, I use that one to time my intervals and I like staring at a screen while I workout. :/ I follow it basically but I jog in the spot during rest intervals and push really hard through active intervals.
I found that according to my heart rate I was burning quite a bit more than Spark indicates for that video, especially after my first 5-10 mins (I do a total of 30 mins). For 30 mins I burn around 300 cals according to my average heart rate and Spark says I burn 240 cals so I just use an average between the two, 280 cals. I'd rather underestimate than overestimate.
Nothing is going to be completely accurate when it comes to calories burned... it's all just estimates really but I did suspect I was burning more than Spark indicated I was because I work in the 75-85% of my max heart rate.
Use slow jumping if you average in the 65-75%, use fast jumping if you average in the 75%+ zone.
Slow jumping burns 80 cals/10 mins (keep in mind I'm using my weight)
Fast jumping burns 100 cals/10 mins
Wow. Cool, never checked this out before but that perfectly aligns with my estimate for cals burned based on my average heart rate. Fast jumping = 300 cals/30 mins. Which is what my heart rate calculator gave me. I guess I'll just use Spark's "Fast Jump Rope" instead of "Coach Nicole's Jump Rope" video to track.

Take your focus off the Marshmallow. www.leangains.com/2010/01/marshmallo
"Toning" is marketing muscles to women who are afraid if they pick up a barbell, they'll leave the gym looking like She-Hulk. It doesn't happen, what does happen is you get results. Lifting Barbie weights does nothing but waste time.
