Body building and kidney infections ?

Hi, welcome to the ehealth forum and I am glad to help you.
You seem concerned if the exercise can lead to UTI.
Exercise itself is not a risk factor for UTI but the only thing that may occur is not drinking enough fluids with the exercise, thus getting dehydrated, having the urine more concentrated and more likely to result in an infection.
Hope this helps. Take care.
