Kegels are often generically given to help strengthen the pelvic floor muscles, but a study in the Journal of Bodywork and Movement Therapies suggests that Kegels alone are not the most effective strengthening strategy.
The study followed twenty-one moms with a recent vaginal birth and tested the pelvic floor activity during six different exercises: a kegel, two core exercises, two inner thigh exercises, and a combination of a kegel, core, and inner thigh exercise. The kegel exercise elicited the lowest pelvic floor contraction as compared to the combo exercise and the inner thigh exercises.
