Logging Gym Exercises

I go to the gym and do strength training for 45min-1 hour. Couldn’t there just be a general calorie range for strength training instead of typing in each exercise? That’s so manual!

    There is. It's in the cardiovascular section of the exercise database, the only part of the database that estimates calorie burn.

    For normal reps/sets workouts with short rests between sets, record the whole session time as "Strength training (weight lifting, weight training)".

    As Ann said above.

    It's a fools errand to attempt to estimate calories per set done. Just use the estimate provided above for total session time. Yeah, it may not seem that high compared to cardio, but that's normal.

    Didn't mention if you have a wearable device/fitness watch. If so, try that. IME, it clocks elevated heart rate from lifting, resulting in a higher calorie burn reading than the much lower default Strength Training Cardio entry in MFP's database.

    But that supposedly higher calorie burn's not a good thing - hoping that's what you mean?

    Lifting doesn't burn a lot of calories. Worth doing for many reasons, but not a high calorie burner during the workout (or from EPOC, in absolute calories vs. percentages).

    Heart rate is a poor indicator of work - calorie burning work in the physics sense of work - during lifting.

    Overall, heart rate sort of works as a proxy for calorie burn because oxygen consumption correlates pretty well with calorie burn, and heart rate is a proxy for oxygen consumption. But heart rate goes up for reasons other than oxygen consumption: Strain, high emotions, ambient heat, Valsalva effects, and more. When heart rate increases during strength training, it's primarily from things like strain and Valsalva effect, not increased oxygen consumption.

    As an aside, heart rate being a proxy - not a direct correlate - of calorie expenditure introduces some other problems, like the obvious difference in heart rate between a very fit person and a very unfit one when they're doing the same activity.

    When it comes to strength training, these days some fitness trackers use METS - same general calorie estimation method MFP uses - in their strength training calorie estimates for exactly these reasons.

    Not a lot of calories, comparatively speaking, and an interesting discussion of the influence of intensity, duration and other variables.
