Jillian Michaels' Formula for Calories Burned

HRM is a Heart Rate Monitor...good on you for asking, I've been on MFP (MyFitnessPal) for almost 3 months now and can't figure out half of the abbrev. that come across these blogs either

170/25 = 6.8
6.8*50 = 340
340/60 = 5.66667 calories per minute.

According to that formula, I would burn 170 calories in 30 minutes.
According to my HRM, I burn 178 calories in 30 minutes.

So not too bad!

According to MFP, "Circuit Training" for 30 minutes burns 308 calories ¬_¬

Woah!

I think if you don't have a HRM, the formula works just as well! MFP is a gross overestimation!

I don't think mine Polar, ft4 had me over 200 , 150 the first time,and I'm in the 160's, 5'6. I think the level one was higher than 2, but she did more weights in level 2. I'll do it again but I would be suspect if 20 minutes was much higher. I ran 2 miles and was not much over that and (the average per mile is 100 in calories) and I don't work out harder than that, just differently.

I think it's a great workout either way, if I'm too low or not, I lost weight and got firmer. I don't eat back my calories at this point so it's not that important to me yet.

I have to think of ripped in 30 and 30 day shred as not just cardio. 2/3 of the video is strength. Yes there is a cardio element to it but she is really wanting to build lean muscle. The more lean muscle you have the more you body has to rev up your metabolic rate to fuel those muscles. That way you are burning calories all day.

I'm not sure if I worked this out right:-

My weight 145lbs divided by 25 = 5.8 (I rounded it up to 6)
6 x 50 = 300
300/60 = 5 calories burned per minute

27 * 5 = 135 calories burned

My HRM consistently said I burned around 170-180 calories for level 1 of 30DS
I'm on day 3 level 2 now and my HRM says I burn around 180-195. I'm not particularly fit so could be why I burn more than the formula.

MFP for circuit training estimates I would burn 238 in 27 mins,

+1
I will read it later.

I'm doing the 40 minute Julian Michaels problem zones video and I know that I burn WAY over 200-400 calories in that amount of time because I am very out of breath and very tired. Its circuit training just like the 30 minute shred so at 5 foot tall and 130 pounds and very in shape I'm guessing anyone that is bigger and less in shape than me is burning up to at least 600-700 calories, I add 600 to my day each day I do this.

Bump

I know this is an older thread, but I noticed some other people have recently bumped so I thought I would post my experience. My formula would be as follows:

129lbs so 130/25=5.2 so 5*50=250/60 minutes=4.167 calories per minute
A typical Jillian workout is 35 minutes including warm up and cool down 35 minutes*4.167 calories=145.83 calories burned.

However, I have a HRM (Polar) and I have seen the following amounts from it:
Ripped in 30 Level 1 175 calories 35 minutes
30 Day Shred Level 2 224/222/178/170/185 calories 26 minutes
Yoga Meltdown Level 1 85 calories 35 minutes
Killer Buns and Thighs Level 1 298 calories 43 minutes

Obviously it varies every time, but I think the HRM is more accurate then My Fitness Pals calculations and I think Jillian's formula is a little low. I also notice my heart rate is higher in the morning than in the evening so the calorie burn depends on the time of day I do my workout. I normally burn more calories when running but the fat burn % is higher with Jillian's workouts then with running. Hope this is helpful

Bump.

Very cool! Thanks posting! I don't have HRM either. It's nice to have a base of what to track for excerise. Even though it could perhaps be on the low side. I rather say I'm burning less than actual than reporting more than actual.

I just did Yoga Meltdown with my BodyMedia for the first time and for 35 minutes at level one it gave me a burn of 120. That seemed low to me but looking around and that is pretty much what everyone else is getting. This seems like an inefficient use of my time. I can go run 3 miles in 30 minutes and burn more then twice that. I guess something is better then nothing.

I don't usually do this, but I was out late Friday and missed my spin class Saturday morning...and did Level 1 instead. I weight 142 and burned 180 calories (mind you, I do the program with 8-10 lb weights)

I was trying out a new HRM yesterday, my second day doing level 1. According to the formula, I should burn 200 calories. Per the HRM, I burned 155. It's probably not surprising that I burned a little less since I can't keep up with all of the cardio work and end up modifying it so that I'm still moving, but less vigorously. (Day 2 was much better than day 1, though!)

I was also wearing my fitbit as always, but I wanted the HRM for the 30DS since it's not really step-based. The two were surprisingly close, so I may not bother with the HRM as I'm a larger-busted lady and the chest strap is not terribly comfortable.

Interesting. The formula indicates I burn only 150 cals in a 30 minute class... But I breathe harder and sweat more than if I do other standard aerobics classes (step or high-lo). Supposedly, 30 min. Of these other typical classes burn about 225 cals (for weight of 150). I think the formula is off.
