• An update of a previous Cochrane review from 2017
• Pelvic floor muscle training can prevent incontinence
• Unclear whether exercises lead to a decrease of incontinence

Performing pelvic floor muscle exercises during pregnancy seems to prevent the development of urinary incontinence, but most likely these exercises do not decrease urinary incontinence that is already present. This is concluded by an international research group that pooled the data of over 10,000 women derived from 46 studies for a Cochrane review.
