cant burn more than 400cals during workout :(

[itsm3]

hi all,

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.

What's your HR getting to during intense parts?  It might be that it's not getting as high as it used to, especially since your RHR is getting so low (not a bad thing, of course, but I know it's frustrating when you're trying to burn those cals!).

my max HR is 183 but i'm in zone 3 when i get to 170ish which i aim to stay within for 50% of the workout. however, it's hard to hit that zone and when i do, it quickly lowers back to zone 2. 

not stresing out over it; i know this is because my fitness level has improved dramatically compared to when i first started but i was just wondering if anyone else has experirenced this.

I have to work a lot harder or a lot longer to burn calories now.  It's a part of getting healthy and fit.

:-O damn i wish to burn 400 calories a work out!!!

It could be that if you are not overweight, and it doesn't take much energy for your body to move, that's why it doesn't burn as many calories. A heavier person, especially one who is out of shape, will burn more calories than you doing the same exercise b/c it takes more energy for them to do the moves; while for you, you are fit and it doesn't take as much energy to complete each exercise.

Do you think you need to up your caloric intake?

[itsm3]

i thought about this and redid my numbers but i'm in the range in which i'm supposed to be and i always eat my calories (or at least close to it)

this is what i'm thinking too.... when i first started, i would burn up to 800+ cals during one insanity workout and now i can only get close to 400cals per insanity workout. 

thanks for your response; was just wondering if anyone else was in the same boat.
