heres where i get confused.
i have tried hiit the last 3 weeks, mixed in with "lower intensity" cardio.
my heart rate during hiit gets up to 162/168 beats per minute, these sessions last about 20 minutes, in which 5 minutes is warmup/5 minutes cool down. so my heart is racing for @ 12 to 13 minutes overall.
on the low intensity days i go 30 minutes keeping my heart rate between 126 and 138 for @ 26 minutes.
am i lead to believe that there is a major difference between the 2? my low intensity cardio is an extremely brisk walk (4.2 to 4.7 mph, sometimes higher). i mean if you look at the 2, my average heart rate is higher for the hiit, but over the duration of the low intensity my heart rate stays higher longer.
this is where i am confused. is there that much of a difference? is my low intensity really more like moderate intensity, therefor more beneficial?
