Whining -- Why doesn't strength training burn more calories?

I've heard the benefits of strength training and been doing it for a while, and I've also heard that somehow it increases your metabolism. But it burns so few calories, especially for someone my size (5'1.5"). I did 30 minutes today, and it burned 81 calories. Sometimes I do a strength training class that's an hour, and I'm sore for 2 days, but burn only 160 calories, and basically can't lift for a couple of days. Wow, I get to "eat back" a yogurt. Whereas if I do cardio like kickboxing and zumba, it burns a ton, but some posts I've seen say that cardio makes you retain fat and lose muscle.

    Who says you only burned X amount of calories? This app?

    The exercise totals for different movements never match up with what they could be in real life.

    Favor weight training when attempting to make body composition changes...

    strength training increases your metabolism in that it preserves lean mass...muscle in particular requires a lot of energy to maintain, so you burn more calories at rest the more muscle mass you have. You also have a greater after burn post lift due to your body has to repair the damage done...that requires energy (calories). Further, strength training is an outstanding investment in your overall body composition, not to mention general health and well being.

    Also, cardio doesn't cause you to retain fat and lose muscle...that is nonsense. I cycle around 90 miles per week and my muscle mass is just fine...

    I've heard the benefits of strength training and been doing it for a while, and I've also heard that somehow it increases your metabolism. by a tiny and pretty insignificant amount unfortunately But it burns so few calories, especially for someone my size (5'1.5"). I did 30 minutes today, and it burned 81 calories. It may well be more but for all practical purposes it's impossible to calculate. Your weight loss results over time may be the best guide TBH. Sometimes I do a strength training class that's an hour, and I'm sore for 2 days, but burn only 160 calories, and basically can't lift for a couple of days. Good for you for putting the effort in!Wow, I get to "eat back" a yogurt. Whereas if I do cardio like kickboxing and zumba, it burns a ton, but some posts I've seen say that cardio makes you retain fat and lose muscle.Myth. You would have to doing a really excessive amount and have a totally insufficient diet for that to be an issue.
    But in the end strength training isn't to burn calories, it's for strength, retention of muscle, to look great when you get to goal and for health.

    Whether it's through calories burned during strength training or calories burned during an after burn I believe it burns much more than MFP thinks it does based on experience.

    Cardio also burns a lot of calories and does not cause muscle loss. Lack of strength training may cause muscle loss.

    Thanks for all the input. I'm certainly not going to stop because I have already lost 1% of my body fat, although the scale's not moving as much as I'd like. BTW, I'm just using MFP's estimate for strength training when I input the time in the tracking log, and that's what they give me because I'm small. Next question, if I lose more weight, won't I be burning even less when I train, rather than more, even if I am building more lean muscle mass?

    Yes...but if you didn't strength train, you would lose more muscle mass which would result in burning even less at the same smaller weight.

    Because strength training isn't about burning calories at that instant. In fact, most people don't even add strength training to their "cardio" exercises on MFP. The general breakdown is:

    1. You're keeping your muscle and losing the fat instead of losing both. It's easier for your body to metabolize protein (muscle) than fat, so if you're not using it it'll go away.
    2. Muscle looks prettier than fat. It's firmer and gives your body a good look.
    3. As the fat burns away and the muscle stays, you see more of that pretty muscle that you've worked so hard to keep. It makes you look prettier, even though you may still be overweight. Example: I have surprisingly nice shoulders even though I'm still 90 pounds overweight, because I've been strength training.
    4. As an added bonus, muscle needs more energy to maintain than fat, which bumps up your BMR. It's more of a long-term effect than cardio.

    Yes, you will burn less as you get smaller, but that's true of cardio as well. Don't do strength training to burn calories. Do it for the sexiness.

    Cardio, especially prolonged sessions, will inevitably result in a loss of muscle mass. You need to have near perfect dietary conditions to prevent that from occurring, or have worked up to a point where thats a common occurrence for you.

    Curious -- what are "near perfect dietary conditions" for cardio to prevent loss of muscle mass?

    Enough protein in your diet. Adequate glycogen levels throughout the duration of the exercise. There could be may factors.

    As mentioned, strength training is for strength. Also for "harder" muscles and lean muscle retention. The benefits of strength training outweigh the lack of calories burned.

    Lift heavy. And get a heart rate monitor to see how many calories you actually burn

    You might want to consider getting a heart rate monitor to more accurately know how many calories you are burning from your strength training sessions. If you log 30 minutes of strength training into MyFitnessPal, it really doesn't know how hard you worked and would tell you the same if you are lifting 5 pound weights vs. 50 pound weights and the same for how many exercises you are actually doing in those 30 minutes. The PolarFT4 heart rate monitor has great reviews.

    This really does not apply to the average Joe/Jane heading out for a run or hopping on the elliptical or doing a zumba class or whatever...

    New question -- how much protein would I need? I read a lot of stuff about certain number of macros being necessary to get a certain type of energy supply and appearance. Maybe this is where I need to to be adjusting since I'm pretty near my goal weight and want to lose body fat. This thread is really educating me.

    1gram of protien for every pound of LBM. I currently try to hit min of 120g.

    and I have to ask what yogurt are you eating at 160 calories??? mine is 50calories a serving...

    For a lot of people who lift we use TDEE and that way we don't have to worry about actual burns...

    not accurate for strength lifting- designed for long stead state cardio.
    Do you have proof of this?
    BECAUSE IT"S A HEART RATE MONITOR- not a calorie counter.

    the heart rate goes up and down while you are lifting- but that the effects are different than running. It's going to say you burn a lot less typically- but just because you are "resting" between sets doesn't mean your body has returned to base line "rest".

    Also: Don't use the strength thing for MFP- it's rubbish and highly inaccurate.

    I use the cardio entry for calisthenics one and kind of ramp it down- if I put in 120 minutes of lifting it would be like 800 calories or something crazy- so instead typically I add my lift in around fraction- usually 45-65 minutes and get a 3-500 calorie burn- which to my body feels about right (comparing to how I feel next to cardio events and what not)

    Be less generous with your workout burns and you'll be fine.

    You are probably burning more than you think if you are really lifting and getting it in.

    If you disagree the onus of proof is on you.

    I used all the necessary verbiage that would allow another variable to introduce itself to change the equation.

    This is a widely known fact. Your calorie burn is not directly attributable to your actual heart rate...your heart rate is simply used in an algorithm by the HRM to determine some level of VO2 max you are working and thus a reasonable estimate of calorie burn at that particular level of VO2 max. To get a good estimate of VO2 max requires an aerobic event...anaerobic events such as weight lifting are ****ty measures of VO2 max and thus HRMs are generally not going to be accurate given that the entire algorithm gets thrown out the window.

    HRMs assume a steady state aerobic event...the further you get away from such an event, the more inaccurate a HRM is going to be for calorie burn estimates.

    Your preferred energy sources are glycogen and fat - not muscle.

    Have a read of this nice simple article, should have enough verbiage for you.....

    The 160 calorie yogurt is the good stuff -- Greek with fruit. If I burn only 80, then I have only 1/2 a cup. Anyway, how do I figure out my "lean body mass". I'm 120 lbs. and allegedly 34% body fat (I'm 55 and female).

    Keep doing strength training. It is important for health, retaining muscle, etc. and it will help you to look better at any weight.

    But for us small gals ( and I mean small in weight as well as height), we will always have to work in some cardio to burn a few more calories so we don't have to be on starvation rations!

    I either go for a walk or short run when I finish my weights, or I do some sort of circuit training. I either use a DVD like Jillian michaels, or if I am doing more straight lifting, after every three exercises or so I will jog in place, jump rope, or do jumping jacks for a minute or two to sneak in some cardio.

    Many on here will tell you that cardio is not necessary but when you are small, middle aged, and female, it just doesn't take many calories to maintain. My sedentary TDEE to maintain is only about 1500 calories. You can make it on 1500 cals without being too hungry, but I like to eat as much as possible, so I work in daily cardio. And if you are trying to create a deficit, it is easy to see why some cardio is good.

    Just my two cents worth!

    bro,bro, bro... Relax, and stop calling me that.

    I never made any claim about the distance one can attain without breaking down muscle mass, but yes, its entirely possible they could burn muscle. What your doing is inferring that im saying they will ONLY burn muscle. Your body preferentially burns circulating nutrients in your blood stream first.

    That would be because your original assertion is, whilst not complete nonsense, not far short of it for your weight loss exerciser.

    Nothing further to add given the link to the article upthread.

    Do both= muscle gainand fat loss

    you are focusing on things that do not "matter" results matter Calorie burn estimations do not
