Doesn't strength training burn calories? Why don't you show any calories burned for strength training?
Estimating the calories burned from strength training is very difficult because it depends on a variety of factors: how much weight you lifted per repetition, how vigorously you performed that exercise, how much rest you took between sets, etc. Because of this, we do not automatically calculate how many calories you burned from strength training exercises.
However, if you'd like, you can add "Strength training" as a cardio exercise to get a rough estimate of how many calories you burned. Please be aware though that this is definitely a rough estimate and can be fairly inaccurate.
