Kegels target the pelvic floor muscles, a group of muscles that stretch like a hammock from your tailbone to your pubic bone at the front of your pelvis. The primary muscle worked is the levator ani, which makes up the bulk of the pelvic floor and consists of three components: the pubococcygeus, puborectalis, and iliococcygeus. But the story doesn’t end there. Kegels also activate deeper connections to your core that most people don’t realize exist.
The Pelvic Floor: Your Primary Target
The levator ani wraps around the entire base of your pelvis. Its job is to support your bladder, bowels, and reproductive organs from below, almost like a muscular shelf. These muscles control your ability to hold urine, manage bowel function, and maintain continence when you cough, sneeze, or lift something heavy. In men, these same muscles help control blood flow to the penis, playing a direct role in erections and ejaculation. In women, they support the uterus and vaginal walls.
The pelvic floor contains two types of muscle fibers, and this matters for how you train it. Slow-twitch fibers handle endurance, keeping a low-level contraction going throughout the day to support your organs against gravity. Fast-twitch fibers kick in during sudden demands, like when you sneeze or jump. A complete Kegel routine works both: slow, sustained holds build up the muscle, while quick contractions build strength for those high-pressure moments.
The Core Muscles That Activate Alongside
When you contract your pelvic floor, you’re not working in isolation. The pelvic floor, the transversus abdominis (the deepest layer of your abdominal wall), and the diaphragm all co-activate as a system. These three muscles work together to regulate pressure inside your abdomen and stabilize your lower spine. The diaphragm connects to the pelvic floor through a layer of connective tissue called the transversalis fascia, which also wraps around the deep abdominal muscles. This physical link means they move in sync.
During exhalation, the diaphragm rises, the deep abdominal muscles contract, and the pelvic floor lifts upward. During inhalation, all three release downward. This coordinated movement transfers pressure smoothly through your trunk and is essential for posture, breathing, and movement control. Contracting the deep abdominal muscles has been shown to increase tonic activity in the pelvic floor, which means core work and Kegel exercises reinforce each other. This is why pelvic floor therapists often incorporate breathing and core stability into their programs.
How to Find the Right Muscles
The biggest challenge with Kegels is making sure you’re actually contracting the pelvic floor and not something else. A common cue is to imagine you’re stopping your stream of urine midflow, or trying to hold back gas. For men, thinking about pulling the scrotum upward toward the body can help isolate the correct muscles. For women, the sensation is similar to lifting and squeezing inward around the vaginal opening.
You can use the stop-urine cue once or twice to identify the sensation, but don’t practice Kegels this way regularly. Repeatedly interrupting your urine stream can interfere with normal bladder function. Once you know what the contraction feels like, practice it while sitting, lying down, or standing.
Muscles People Mistakenly Work Instead
One of the most common errors is tightening the wrong muscles entirely. People frequently squeeze their glutes, clench their inner thighs, or brace their abdominal wall instead of engaging the pelvic floor. If you notice your buttocks lifting off the chair, your belly pushing outward, or your thighs pressing together, you’re compensating with the wrong muscle groups. The pelvic floor contraction should feel internal, like a subtle lift and squeeze deep inside the pelvis, with minimal visible movement on the outside.
Holding your breath is another red flag. Since the diaphragm and pelvic floor work together, bearing down or holding your breath can actually push the pelvic floor downward rather than lifting it. Breathe normally throughout each contraction.
A Standard Kegel Routine
A typical protocol calls for three sessions per day. Tighten your pelvic floor muscles, hold for three to five seconds, then relax for three to five seconds. Repeat 10 times per session, aiming for morning, afternoon, and evening. As the muscles get stronger, you can work up to holding for 10 seconds at a time. Mix in quick contractions as well: squeeze and release as fast as you can for 10 repetitions to train the fast-twitch fibers.
Most people notice improvement in bladder control and muscle awareness after six to eight weeks of consistent daily practice. Like any muscle, the pelvic floor responds to progressive training, so starting with shorter holds and building up is perfectly fine.
When Kegels Can Do More Harm Than Good
Not everyone benefits from strengthening the pelvic floor. Some people have a hypertonic pelvic floor, meaning the muscles are already too tight and can’t fully relax. This can cause pelvic pain, difficulty urinating, painful intercourse, or a feeling of constant tension in the lower pelvis. For these people, doing more Kegels adds tension to muscles that are already in spasm, making symptoms worse. The fix in those cases is learning to relax and lengthen the pelvic floor, often with the guidance of a pelvic floor physical therapist. A key rule: Kegels should never cause pain. If they do, that’s a sign the muscles may need release work rather than strengthening.
