I lift for an hr. and a half every other day... I have noticed that as I get further in(after 1 hr. of lifting I am breaking a sweat...) my face turns red and I sweat. Should this occur with weights? I thought it was solely cardio.

Yes, it is normal to sweat while lifting weight, especially if you do compound lifts like squats and deadlifts, it also depends heavily on the temperature in the room. I sweat a lot more in the summer.

The reason why you sweat is to maintain your body temperature at around 37 degrees, when you use energy in any way, you will be pushing your temperature upwards, meaning you have to compensate with sweat to keep it steady.

Running usually uses more energy than weight lifting, but when you run, you get a greater cooling effect because the air is typically colder than you are, meaning you won't sweat as much as you might think you would.


It is very normal to sweat during a weight lifting training and even necessary for the body to cool off during the workout.

When you workout your body need extra energy to do the training, it burns more fuel, it creates more heat and thus needs to cool itself = sweating.

You usually sweat more in cardio because you burn more, but also in weight lifting.

Frankly, I think you should be worried if you don't sweat. That might tell you you don't work hard enough, or something isn't so good.

  • So you're saying I should worry when I don't sweat much during the winter or focus on technique? Sweating bears no indication on how well a workout was done, only that the body's temperature was high enough that it needed cooling.

    -1. You don't sweat more because you burn more. Otherwise all we would need to do to lose weight would be sit in a sauna. Sweating is solely related to needing to cool the body.

  • As anecdotal evidence, today I squatted for a heavy double at 96% of my 1RM and then did 3 back off sets at 75% of that and didn't sweat until after I was into my second set of SLDL's after being completely finished with squats. I'm pretty sure I worked plenty hard enough with my squats.
