Can a person undo cardio work by lifting weights during the same workout?

Question by wyldflwr34: Can a person undo cardio work by lifting weights during the same workout?
I’ve heard it said that a person can undo the good they are doing by a good cardio work out – if they go after that and lift weights…in the same time period. Is that true?

No and yes. You can’t undo the fat loss since weights also make you lose fat
However, cardio deteriorates muscles and weights increase them which negates muscle loss and growth so you’ll stay the same muscle wise that is. Yes you’ll lose fat still
