What Muscles Do Kegels Work? Complete Anatomy Guide

Kegel exercises target muscles most people can't see and rarely think about—until there's a problem. The pelvic floor is foundational to core function, bladder control, sexual health, and more. Understanding pelvic floor anatomy helps you train these muscles effectively, whether for rehabilitation or prevention.

The Pelvic Floor: What It Is

The pelvic floor is a hammock-like group of muscles that spans the bottom of your pelvis. It supports your pelvic organs and controls several important functions.

Think of it as: The bottom of your "core canister"—diaphragm on top, pelvic floor on bottom, abs and back around the sides.

Muscles Targeted by Kegels

The Levator Ani Group

The main pelvic floor muscles, consisting of three parts:

Pubococcygeus:

• Largest portion
• Runs from pubic bone to tailbone
• Primary muscle trained in Kegels

Puborectalis:

• Sling around rectum
• Controls bowel function
• Contributes to continence

Iliococcygeus:

• Thinner, lateral portion
• Supports pelvic organs
• Assists other levator muscles

The Coccygeus

Posterior pelvic floor muscle:

• Runs from ischial spine to coccyx
• Supports tailbone area
• Assists levator ani

External Muscles

Superficial pelvic floor muscles also involved:

• External anal sphincter
• Urethral sphincter
• Muscles around genital area

Related Muscles (Indirect)

Kegels also affect:

• Transverse abdominis: Works with pelvic floor
• Multifidus: Deep back stabilizer
• Diaphragm: Moves in coordination with pelvic floor

Functions of the Pelvic Floor

Support

Holds up pelvic organs:

• Bladder
• Uterus (in women)
• Rectum

Weakness can lead to prolapse (organs dropping).

Sphincter Control

Controls openings:

• Urethral sphincter (bladder control)
• Anal sphincter (bowel control)

Weakness leads to incontinence.

Sexual Function

Contributes to:

• Sensation
• Orgasm
• Erectile function (men)
• Vaginal tone (women)

Core Stability

Part of the core system:

• Works with diaphragm, abs, back
• Creates intra-abdominal pressure
• Stabilizes spine during activity

Circulatory Support

Assists blood and lymph flow:

• Muscle pumping action
• Supports venous return

Who Benefits From Kegels?

Women

• Pregnancy and postpartum: Supports growing uterus, aids recovery
• Menopause: Counters hormonal changes affecting tissues
• Prolapse prevention/management: Supports organs
• Incontinence: Improves bladder control
• Sexual function: Enhances sensation and satisfaction

Men

• Post-prostate surgery: Rebuilds continence
• Erectile function: Improves blood flow control
• Incontinence: Addresses leakage
• Core strength: Part of complete core training

Everyone

• Athletes: Core stability and injury prevention
• Those who sit: Counters pelvic floor weakening
• Heavy lifters: Supports intra-abdominal pressure
• Preventive health: Maintains function before problems arise

How to Perform Kegels Correctly

Finding the Muscles

For beginners, identify by:

• Stopping urine mid-stream (only to identify—don't do regularly)
• Imagining stopping gas
• Feeling a "lift" sensation internally

What you should feel:

• Internal squeeze and lift
• NOT abdominal clenching
• NOT buttock squeezing
• NOT breath holding

Basic Kegel Technique

1. Squeeze: Contract pelvic floor (lift up and in)
2. Hold: 3-10 seconds
3. Relax: Full release (equally important)
4. Rest: Equal time to hold
5. Repeat: 10-15 repetitions
6. Sets: 3 sets per day

Progression

Beginner:

• 3-second holds
• 10 reps, 3x daily
• Focus on finding muscles

Intermediate:

• 5-10 second holds
• 15 reps, 3x daily
• Add quick flicks (fast contractions)

Advanced:

• 10-second holds
• Incorporate into activities
• Add resistance (devices available)

Common Kegel Mistakes

Bearing Down Instead of Lifting

Problem: Pushing out instead of lifting up Fix: Focus on "elevator going up" cue

Using Other Muscles

Problem: Squeezing abs, glutes, or thighs Fix: Isolate pelvic floor, keep everything else relaxed

Holding Breath

Problem: Creates excessive pressure Fix: Breathe normally throughout

Only Squeezing, Not Relaxing

Problem: Creates tension patterns Fix: Full relaxation between reps is essential

Doing Too Many

Problem: Muscle fatigue, tension Fix: Quality over quantity—3 sets of 10-15 is plenty

When Kegels Aren't Enough (Or Aren't Right)

Pelvic Floor Physical Therapy

Consider if:

• Can't find the muscles
• Symptoms not improving
• Pain with Kegels
• Complex issues (prolapse, significant incontinence)

PT can provide:

• Biofeedback
• Internal assessment
• Personalized program
• Manual therapy

Pelvic Floor Tension (Hypertonic)

Some people need to RELAX, not strengthen:

• Pelvic pain
• Painful intercourse
• Difficulty emptying bladder
• Chronic tension

Kegels can worsen hypertonic floors—relaxation and "reverse Kegels" may be needed instead.

Kegels and the Core Connection

The Pressure System

Pelvic floor works with:

• Diaphragm (top of core)
• Transverse abdominis (front)
• Multifidus (back)

During proper breathing:

• Inhale: Diaphragm descends, pelvic floor gently lowers
• Exhale: Diaphragm rises, pelvic floor gently lifts

Integration With Exercise

For lifting and exertion:

• Exhale on effort
• Pelvic floor naturally engages
• Avoid excessive breath holding (Valsalva)

Signs of poor integration:

• Leaking during exercise
• Pressure or bulging sensation
• Inability to maintain core control

Results Timeline

What to expect:

• 2-4 weeks: Better awareness and control
• 4-8 weeks: Noticeable improvement in symptoms
• 3-6 months: Significant strength gains
• Ongoing: Maintenance required (use it or lose it)

The Bottom Line

Kegels work the levator ani muscles (pubococcygeus, puborectalis, iliococcygeus) and coccygeus—the muscular hammock of your pelvic floor. These muscles control bladder and bowel function, support pelvic organs, contribute to sexual function, and are essential to core stability.

Proper technique matters—lifting, not bearing down, with full relaxation between reps. Most people benefit from Kegels, but some need relaxation work instead.

The pelvic floor is foundational. Strengthen it before problems arise, or rehabilitate it when they do.

Kegel exercises target muscles you can't see but use constantly. Understanding pelvic floor anatomy helps you train these muscles effectively for continence, core function, and overall health.
