What Weakens Pelvic Floor Muscles?

Many people experience pelvic floor weakness, which can lead to discomfort, pain, and incontinence. Pelvic floor muscles are responsible for supporting the bladder, uterus, and rectum, so it is essential to keep them strong. Weak pelvic floor muscles can be caused by various factors, including pregnancy, aging, and obesity.


During pregnancy, the pelvic floor muscles are put under a lot of strain. The growing baby puts pressure on the pelvic floor, which can weaken the muscles over time. The hormones produced during pregnancy can also lead to relaxation of the muscles, making them more vulnerable to injury.

After childbirth, the pelvic floor muscles can take time to heal and recover. Women who have had a vaginal birth are more likely to experience pelvic floor weakness than those who have had a cesarean section. It is important for women to seek treatment if they experience any symptoms of pelvic floor dysfunction after giving birth.


As we age, our muscles naturally weaken, including the muscles in the pelvic area. The tissues that support the pelvic organs can also become less elastic and more fragile, making them more susceptible to injury. Hormonal changes during menopause can also contribute to pelvic floor weakness.


Being overweight or obese can put extra pressure on the pelvic floor muscles, leading to weakness over time. Carrying excess weight can also make it harder for the muscles to contract properly, which can lead to incontinence and other issues.

Chronic Constipation

Chronic constipation can also contribute to pelvic floor weakness. Straining during bowel movements can put a lot of pressure on the pelvic floor muscles, which can cause damage over time. This can lead to incontinence, pelvic pain, and other problems.

High-Impact Exercise

High-impact exercises such as running and jumping can also weaken the pelvic floor muscles, especially if proper form is not used. It is important to engage the pelvic floor muscles during exercise to help prevent damage.

What Can You Do to Strengthen Your Pelvic Floor?

Fortunately, there are many things you can do to strengthen your pelvic floor muscles and reduce the risk of pelvic floor weakness. One of the most effective ways to do this is through stability ball training.

Using a stability ball, also known as a Swiss ball or exercise ball, can help activate and strengthen the pelvic floor muscles. The unstable surface of the ball makes it more challenging to maintain your balance, which forces your muscles to work harder.

Exercises to Try on a Stability Ball

Here are some exercises you can try on a stability ball to help strengthen your pelvic floor muscles:

Exercise Instructions
Pelvic Tilt Start by sitting on the ball with your feet flat on the ground. Slowly rock your hips forward and backward, focusing on engaging your pelvic floor muscles.
Bridge Lie on your back with your feet on the ball. Lift your hips off the ground, pushing through your feet and squeezing your glutes and pelvic floor muscles.
Kneeling Push-Up Start in a plank position with your hands on the ball and your knees on the ground. Lower your chest toward the ball, keeping your core and pelvic floor engaged.
Single Leg Lift Start by lying face down on the ball with your hands on the ground. Lift one leg up behind you, squeezing your glutes and pelvic floor muscles.


Pelvic floor weakness can cause a lot of discomfort and can even impact your quality of life. By understanding what weakens these muscles, you can take steps to prevent this from happening. Stability ball training is an effective way to strengthen your pelvic floor muscles and reduce the risk of pelvic floor weakness. Try incorporating these exercises into your workout routine and see the difference they can make.
