Eating back strength training calories?

You can enter strength training for cardio...

Wait, I'm confused. When I enter strength training (under cardio), it gives me calories burned.

Yeah I track mine in cardio using my HRM and eat them back. I think my diary is public, if you wanna check it out.

I saw that in FAQs but it can also be very inaccurate?

It's inaccurate if you aren't using a Heart Rate Monitor (HRM). I use a HRM so I know exactly how many calories I burned and I enter that into the cardio under the DVD that I did, I'm using Chalean Extreme.

You will not get an accurate calorie burn on an HRM during strength training. The exercise is too focused on one body area as opposed to cardio when your whole body is moving. Also, the heart rate goes up during strength training due to the PRESSURE exerted on the heart by strenuous activity. In cardio, your heart rate goes up due to increased FLOW of blood. Your uptake of oxygen also has an effect on calorie burn and it simply isn't as high during strength training as it is in cardio.

I log my strength workouts under cardio, but I discount the burn by 33%...If I burn 1000 calories on the HRM, I log 666. The general rule of thumb is 30-35% discount on the burn...I split the difference and go 33%....it has worked for me...I am maintaining an average per week weight loss of around 1.8pounds.

WTF, Bob?! I lift for an hour and it tells me I burn 242 calories. In the whole hour. I burn 670 an hour doing cardio. Should I reduce the 242 by 33%?! OMG. *cry*

I set my activity level as sedentary and I log all my exercise calories (strength and cardio) via my heart rate monitor. I eat back my calories. I've never compared my HRM readout to the manual options, but I'm sure there's a discrepancy between the two because 'weight training' or 'circuit training' can mean totally different things depending on your workouts.

Heart rate monitors are accurate for ANY activity as long as you're in one of the three HR zones. They're not calibrated for calculating calories below 50-55% of your max heart rate, so in that case they'd be inaccurate (this only applies to heart rate monitors you wear for working out, the ones you wear all day, like Bodybugg, work differently).

FWIW, most people don't exert extreme amounts of pressure during weightlifting unless they've got bad form or they're holding their breath (AKA Valsalva maneuver, which should only be done by professionals, and yes it raises your blood pressure).

I'm confused by this, are you suggesting my HRM is in accurate as to the calories burned during my strength training?

I'm confused too Bob, I was going to go with what you said if I can understand it correctly, but I'm not so sure.
Overall consensus? Wear a HRM during strength training and, when logging my exercise, log it as cardio but reduce the calories by 33%. Yes?

I didn't pull this out of my you-know-what...there is a guy on here who is an exercise physiologist that is very knowledgeable on this subject and I trust what he says implicitly. In the simplest of terms, an HRM does not have the proper ability to record an accurate calorie burn with strength training. You are reduced to best guess and the best guess is 2/3 of the burn or 66% of the burn. All I know is it works for me...feel free to choose as you see fit. I am deathly afraid of overeating my exercise calories back and this is my way of ensuring that I do not do that...

Yes, that is what I am saying at least...try it for a few weeks and see what kind of results you get on the scale and with a tape measure from where you are now.

I only do a bowflex routine for 20 minutes a day maybe 1-3 days a week. I don't bother logging any of them. Don't really burn enough calories to bother. All I know is if I go over my calorie goal a little bit I know I'm still good because of the exercise.
