Brittany Mahomes Isn’t Wrong: A Weak Pelvic Floor *Can* Contribute to a Back Fracture

One useful takeaway here is that pelvic floor weakness can be part of a broader postpartum core problem, not a stand-alone diagnosis. The pelvic floor works with the diaphragm, abdominal wall, hips and spinal stabilizers. When that system is disrupted, everyday loads — lifting, twisting, coughing, getting up from the floor — may feel harder to control. That makes the idea of back symptoms plausible, but it does not prove a single weakness directly caused a fracture.

The distinction between correlation and causation matters. A back fracture can have many contributors, including pregnancy-related mechanical strain, bone health, impact, training load and recovery patterns after childbirth. Social media stories often compress a complex chain of events into one headline-friendly cause. For readers, the safer interpretation is that pelvic floor dysfunction may be one factor in a larger musculoskeletal picture, especially after pregnancy, rather than the only explanation.

There is also a practical caution around self-directed “fixes.” Kegels are commonly discussed, but they are not automatically the right answer for everyone. Some people need strengthening, while others need better relaxation, coordination or help with breathing and pressure management. Pelvic floor care is most useful when it is individualized, because symptoms such as leakage, pain, constipation or return-to-exercise difficulty can reflect different problems.

The broader message is less about celebrity and more about rehabilitation literacy. Postpartum recovery is not just “getting back in shape”; it is rebuilding movement control, tissue tolerance and confidence. For anyone with persistent pelvic, tailbone or low-back symptoms, the key question is not whether a workout is intense enough, but whether the body can distribute force well during daily life and exercise.

Brittany Mahomes, the wife of Kansas City Chief quarterback Patrick Mahomes, has an important PSA. In an Instagram story this week, she shared she’s been diagnosed with a fractured back, alluding that it’s due to a weak pelvic floor. “Just a daily reminder: Once you have kids please take care of your pelvic floor. Seriously,” Mahomes wrote. “From: A girl with a fractured back,” wrote the mother of two. Pelvic floor health is essential to bladder and bowel control, childbirth, sexual function and other functions of daily living, according to the National Association for Continence. But can a weak one really lead to a fractured back? Yes, experts say (eek!). We chatted with a physical therapist to explain why a weak pelvic floor can lead to a back injury, and the best ways to prevent it.

What is the pelvic floor?

The pelvic floor is a group of muscles that supports and protects vital organs—like the bladder, bowels, and uterus, per the Cleveland Clinic. When these muscles are not working efficiently, you can experience bladder and/or bowel leakage, pelvic pain, and other concerns. “The pelvic floor muscles also form the interior border of our core, and help contribute to the stabilization of the spine, pelvis, and kinetic chain during functional movement,” explains Kari Melby, DPT, a physical therapist and senior director, specialty services at ATI Physical Therapy. “This helps coordinate movement of the arms, legs, and spine required with day-to-day tasks and exercise.” Reminder: Your core isn’t just your abs—it also includes your pelvis, lower back, hips, and stomach, per the Mayo Clinic. Strong pelvic floor muscles lead to better stability and strength for physical activities, like playing sports or working out, and daily tasks. Weak pelvic floor muscles can result in injuries.

How can a weak pelvic floor result in a back fracture?

Mahomes did not reveal the exact cause of her back injury, but linked the injury to pelvic floor issues she’s had since having children. While Melby isn’t familiar with the specific details of Brittany Mahomes’ back fracture, she explains that the pelvic floor muscles are vital to one’s core strength and the ability to return to exercise and strength training following childbirth. “Though the body is designed to accommodate the needs of pregnancy and childbirth, it still puts stress and strain on the muscles, tissues, and bones in the pelvis and abdomen, which may lead to symptoms and concerns that impact one’s daily life,” Melby says. The pelvic floor is connected to the tailbone and your lower back. If those muscles are weak, the tailbone weakens, too, creating instability and potentially contributing to a back fracture. There are major benefits to strengthening pelvic floor muscles after giving birth. Seeing a pelvic health specialist can help with weakness, aches and pains in the pelvis, bladder and bowel leakage, and sexual health concerns.

How to maintain a healthy, strong pelvic floor

Melby says the best thing to do is to consult with a specialty-trained pelvic health physical therapist to receive the most accurate exercises to address your individual needs. Exercises may include:
  • Pelvic floor muscle contractions (aka Kegels): The ability to properly contract (squeeze and lift) and also fully relax the muscles in the lower pelvis. Do this while sitting, standing and lying down, and squeeze the muscles of your pelvis. Pull your navel to your spine, hold for 1 to 2 seconds then quickly release. Repeat at least 10 times for each position.
  • Happy baby tailbone stretch: This yoga pose provides a range of benefits for those experiencing tailbone pain. Do this by lying on your back with your head and shoulders on a mat or the floor. Bend your knees towards your chest with your feet flexed, without allowing your shoulders to leave the mat and without straining your neck. Reach forward and grab your shins, ankles or the insides of your feet. Allow your legs to drop gently open and hold this position for several breaths. If you feel comfortable, you can also gently rock from side-to-side, hold this position for 30 seconds to one minute.
According to Stanford Medicine, other strategies to improve pelvic floor health include:
  • Guided meditation to help loosen overly tight pelvic muscles
  • Avoiding constipation by drinking plenty of water, eating fiber-rich foods, and exercising regularly
  • Avoiding straining or pushing during bowel movements and when urinating
  • Cutting back on caffeine, alcohol and artificial sweeteners
  • Learning how to relax the muscles in the pelvic floor area
Brittany Mahomes has never neglected her overall fitness routine: She’s a certified personal trainer with her own workout program, Brittany Lynne Fitness, and will be in the upcoming swimsuit issue of Sports Illustrated. It’s clear that prioritizing pelvic floor health goes beyond your workouts, though those are important. And focusing on pelvic floor health isn’t just for new moms—it’s for everyone, Melby explains. These muscles influence many important aspects of the body including bladder and bowel health, sexual intimacy, and core strength. “It’s common practice to receive rehab following traditional surgeries or injuries involving one’s knee, back, shoulder, etc. to make sure the muscles are moving and activating correctly,” she says. “Your pelvic floor muscles should receive the same attention!”
