cant burn more than 400cals during workout :(
i've been doing beachbody
programs for over a year, hit all of my fitness goals and continue to
push/challenge myself fitness-wise. i like to consider myself physically
fit because of all the hard work i've done....i've completed insanity,
asylum/p90x hybrid and currently mixing up body beast with asylum/GSP
rushfit. i eat clean 24/7 with no cheating and i always eat within my
daily caloric range.
i have a polar ft60 HRM which i wear during every workout (with chest strap). my resting heart rate when i first started my fitness journey last year was close to 80bpm. i rechecked my resting heart rate last week (twice, just to make sure) and did it when i woke up; both times i did it, it said my resting heart rate is 60bpm.
the problem (?): i cannot burn more than 400 cals during any workout! i feel challenged during workouts (esp during insanity workouts) and last week, i did a 60minute kettlebell/tabata class that was really tough. i did the full 60mins with no extra breaks (only three one-minute breaks were allocated) and at the end of the workout, i looked at my HRM and i only burned 392cals!
just wanted to know if anyone else is in this boat and if this is normal.
