Strengthen your hips and glutes

"The pelvic floor is a helper muscle, and it loves to take over and help stabilize the body when your hips or glute muscles aren't doing their job," says Dunfee. But the pelvic floor will easily fatigue and stop working correctly.

If weakness in these areas is a problem, exercises such as squats, lunges, dead lifts, bridges and hip thrusts can all help. For runners, focus on single-leg exercises whenever you can since running is a single-leg dynamic activity.
