I do cardio on a treadmill that has an "interval" setting which varies the degree of incline. I walk at 2.5 mph at inclines of 2% up to 6.5%, 3-4 minutes at each incline, dropping to zero between the varying levels. My heart rate builds up to anerobic by the time I am at the highest incline. According to my Polar heart rate monitor, I am burning about 600 calories per 48 minutes. I do like it very much! I am almost 70 and struggling to lose 50 pounds. I am wondering tho, if this counts as HIIT.
