Well interesting indeed...
Wednesday night I did typical evening asanas, 1A/8 breaths DD and 2Bs/also 8 breaths DD. Here's the heart rate numbers (I adjusted it for my personal stats, height, weight, sex etc):
7.27 Time
.52 In Zone (118-155)
102 Average
40 Calories burnt
60% Of them were fat
GAS last night me Christine and Siddhu. Did 3As and 3Bs, fundies, and sitting up to MarichiA, followed by final 4 poses, and Christine wore the monitor (I adjusted it for her stats):
43.43 Time
122 In Zone (118-155)
90 Average
39 Calories burnt
60% Fat
Correct breathing accounts for a great difference in the cardiovascular effort required to do ashtanga asanas (Christine is a much more experienced ashtangi). Or likely so does physical size (Christine is a much smaller ashtangi). Or is there a really an unfair difference between the sexes? [gender is an important factor in how calorie burning is measured]
I swear I'm not obsessed with the HR monitor... just goofing around...
