Kegel exercises strengthen the pelvic floor muscles that support the bladder and bowel.
The pelvic floor is a layered group of muscles and connective tissues stretching across the bottom of the pelvis. It helps support pelvic organs and contributes to urinary and fecal continence. Kegels train these muscles by repeatedly tightening and relaxing them, much like strength training for an internal support system.
American gynecologist Arnold Kegel described the exercises in 1948 while developing treatment for urinary incontinence. They are used by people of all sexes and may be helpful during pregnancy, after childbirth, or after prostate treatment. Regular practice can take several weeks or months before benefits become noticeable.
A common mistake is repeatedly stopping urine flow as the exercise itself. That may help identify the muscles once, but doing it regularly can interfere with normal bladder emptying. The intended contraction is the one used to prevent passing gas and urine at the same time. Kegels are not abdominal, hamstring, or lower-back exercises, although other muscles may tense accidentally if the technique is poor.
