I scanned through the first video you shared, and it looks like pretty much straight bodyweight strength training, with a little yoga-like stretching thrown in. I would track it as strength. It doesn't have the rhythmic moving that I would consider to be cardio at all... so I wouldn't track it as dancing, because you're not really doing cardio with that one.
The second one (I didn't look but a little but at that one) seems to be mostly the same, with some low-impact cardio. So I'd track all of that as strength, and no worry about the HRM for it... it's strength, and an HRM won't provide you with an accurate calorie burn. There are a few portions where they seem to be doing a little moving, if you want to track those separately I'd use low-impact cardio.
It does look like a REALLY fantastic workout though... good choice! Strength of this nature will help you look and feel great, even though it's not a *huge* calorie burner, it provides more long-term calorie burn by building muscle and boosting metabolism.

Writer, mother, wife, and breadwinner. I love to run, but running doesn't love me, so I'm switching to my low-impact bike.
