Calories from strength training?

I log them, but I don't eat them back. From what I gather, calories burned from strength training are hard to calculate, so I just enter them more to keep track of how much time I am spending lifting, and less to track calories.

Good luck!

I don't log mine, I only log for cardio

I log a small amount for mine (like 50 calories per half an hour)

Here is a method that will get you in the ballpark. Maybe only in the city of the ballpark...

What you can do in lieu of a HRM is estimate the number burned based on your average heart rate for the time spend lifting.

Here is a formula...

For males:
C = (0.6309 x H + 0.09036 x W + 0.2017 x A — 55.0969) x T / 4.184.

For females:
C = (0.4472 x H — 0.05741 x W + 0.074 x A — 20.4022) x T / 4.184.

C = calories burned
H = average heart rate
W = your weight
A = your age
T = the length of your exercise session in minutes.

An example:
Assume that you’re a 28-year-old female weighing 146 pounds. Your average heart rate during an exercise session that lasted 36 minutes was 138 bpm. You burned C = (0.4472 x 138 — 0.05741 x 146 + 0.074 x 28 — 20.4022) x 36 / 4.184 = 301 calories.

I hope this helps. I haven't got a heart monitor either.

Oh...here is how I track it:
1) I used the formula to determine my calories for 30 minutes. I guessed low on the average heart rate. I think I picked 90 bpm when I know it was over that! I have been hitting the weights pretty hard twice a week.
2) I created a Cardio exercise in MFP called weight lifting.
3) I use that each time I have a weight session.

It gives me some extra calories on those days. It's not 100% accurate but at least it's a little bit low so if I go over on my food log on those days I sleep well that night.

I just estimate under the "circuit training general." I eat enough to keep me energized and not feeling "hungry." Sometimes I eat none, little, some, or all of my exercise calories based on hunger. I am hesitant sometimes to eat all because it being such a rough estimate.

Wow, that's very elaborate! How did you come up with this formula? Is it more accurate than HRM?

Is height in inches or?

Aryastark - I just Googled and read some websites and one of them had the formula. It would be less accurate than a good HRM. I just wasn't sure where the numbers on MFP were coming from.

HonkyTonks - height is not required sweetie.

I wear a polar FT7. I also train 'circuit style'...but I use my heartrate as my guage, not a watch. When my heart rate drops to somewhere between 130 and 140 (depending on how much it elevated), I start my next set. The only cool down between exercises is walking to the next lifting station, and setting it up. Other than that...it's continuous.

As a brief breakdown, this was my last three workouts, time vs calories burned:

5/9/12 - Workout B - 647cal/54min
5/7/12 - Workout A - 588cal/46min
5/4/12 - Workout B - 634cal/49min

Additionally, I use another method to calculate my deficit than MFP (lifting days is +20%/TDEE, off days -20%/TDEE), so I don't eat back my exercise calories either.

I think I might love you, seriously.

Ahh, but unfortunately my lovely LemonBurns...you're married, and probably live halfway across the planet anyway...

/sigh!

strength training is unique because your muscles are going to be burning calories after the fact as they grow...theres not an accurate way to measure calories burned, but u definitely want to fuel up afterwards to give ur muscles stuff to grow from! but that being said,strength training especially lifts that use multiple muscles (squats,deadlifts, etc) are GREAT for getting your heart rate up if ur worried about that. also if ur trying to get cardio in, try circuit training!

This is very true. There are also other, hormonal benifits that come with heavy lifting that are immeasurable when compared to just calories burned.

For the record though, I only use my lifting calories as a guage of my intensity...as I said, I use another program than MFP to calculate my deficit. MFP is just for tracking and the wonderful atmosphere .

there is "strength training, weight lifting" in cardio part+elliptical training is count as this. I do strength trianing 50% now, but log it mostly to cardio

bumping, til I can read later
