Glute Bridge — Pelvic Floor Focus Only: A Complete Guide to Flat-Lying Pelvic Floor and Glute Co-Contraction

Quick Intro

Glute Bridge — Pelvic Floor Focus Only is a pelvic floor exercise done lying supine with the knees bent, squeezing the glutes and pelvic floor together without lifting the hips off the floor. It’s an isolated entry point, built to feel the co-contraction pattern clearly before the hip-lifting bridge itself is added.

Equipment Needed

No equipment is required, though a mat under the hips softens the surface for this lying-down position.

Why It Matters

Squeezing the glutes and pelvic floor together while staying flat asks for a true co-contraction, even without the added load of lifting the hips. This works the pubococcygeus and iliococcygeus (the two main pelvic floor muscles) together with the gluteus maximus (the largest glute muscle), a pairing that carries directly into the full bridge exercise this one leads into. Feeling that pairing clearly while flat on the floor matters because the bridge itself adds a hip lift on top, and the co-contraction is easier to isolate without that extra demand. The transverse abdominis (the deep core muscle wrapping the trunk) stays active in the background through the whole squeeze, as it does with most pelvic floor work.

When to Do It

This fits well as a first step for anyone learning to feel the glute and pelvic floor working together, before attempting the full bridge, and a short daily session on the floor is all it takes to build that awareness. Anyone with pelvic pain or a diagnosed pelvic floor disorder should get individual guidance before adding co-contraction work of any kind.

Getting Ready

No physical warm-up is required. Lie down with the knees bent and feet flat, and take a breath or two before the first squeeze.

Step-by-Step Instructions

1. Lie supine with knees bent, feet flat and arms relaxed at the sides.
2. Squeeze the glutes and pelvic floor together, without lifting the hips off the floor.
3. Hold the combined squeeze for a few seconds, keeping both muscle groups equally engaged.
4. Release both together, letting the hips and pelvic floor return fully to rest.
5. Repeat the squeeze-and-release cycle, checking that the two muscle groups fire at the same time.

How Many, How Often

Feeling both muscle groups fire together matters more here than reaching a specific rep count.

Modifications and Variations

This exercise is the easier form of Glute Bridge with Pelvic Floor Engagement.

Harder: Glute Bridge with Pelvic Floor Engagement. Adding the hip lift on top of this same co-contraction is the direct next step once the squeeze itself feels reliable.

Common Mistakes to Avoid

Squeezing the glutes noticeably before or after the pelvic floor. The point of this exercise is a true co-contraction, not two separate squeezes happening close together.

Trying to lift the hips before the squeeze feels solid. Adding the hip lift too early skips the isolated practice this exercise is meant to provide.

Rushing the release. Letting go abruptly rather than in a controlled manner skips half of what the exercise is meant to train.

After Your Set

Nothing here needs an outward stretch afterward. Letting the hips and pelvic floor fully soften for a minute of relaxed breathing closes out the set.

Going Deeper

The most common reason this doesn’t progress well is moving straight to the hip-lifting bridge before the co-contraction itself feels reliable while flat on the floor. Progress here looks like the glutes and pelvic floor firing together consistently, which is the foundation the full bridge exercise depends on once the hip lift is added.

How to Know You’re Improving

1. The glutes and pelvic floor fire together rather than one noticeably before the other.
2. The hold can be sustained without either muscle group fading.
3. The release feels as controlled as the squeeze itself.
4. Breathing stays normal throughout, without holding.
5. Adding the hip lift feels like a natural next step.

Muscles Worked

• Pubococcygeus (one of the two main pelvic floor muscles, firing at the same moment as the glutes with no hip lift to follow)
• Iliococcygeus (the second main pelvic floor muscle, learning the timing while the body stays flat)
• Gluteus Maximus (the largest glute muscle, squeezing without moving the pelvis off the mat)
• Transverse Abdominis (a deep core muscle that wraps around the torso like a corset, joining the co-contraction gently)

FAQ

Why practice this flat on the floor instead of going straight to the bridge? Staying flat removes the extra demand of lifting the hips, making it easier to feel the glutes and pelvic floor firing together before that co-contraction gets combined with a hip lift.

What comes after this feels reliable? Glute Bridge with Pelvic Floor Engagement adds the hip lift on top of the same co-contraction, the natural next step for anyone comfortable with this pattern.

Is it normal for one muscle group to feel stronger than the other at first? Yes. Feeling the glutes more clearly than the pelvic floor, or the reverse, is common at first and tends to even out with practice.

Does this replace the full bridge exercise entirely? No. This is a preparatory step, and most people move on to the full bridge once the co-contraction itself feels solid.

What does a co-contraction mean here? Two muscle groups tightening at the same time on purpose. In this exercise the glutes squeeze while the pelvic floor lifts, and the aim is for both to switch on together and both to switch off together, with neither leading.

Should the hips move at all? No. The pelvis stays resting on the floor for the whole squeeze. If the hips start to rise, the glutes are doing more than this version asks for and the exercise has drifted toward the bridge it is meant to prepare for.

How hard should the squeeze be? Firm enough to feel both muscle groups clearly, and no harder. A moderate squeeze makes it easier to notice whether the pelvic floor is joining in, since a maximal glute clench tends to drown out the smaller sensation underneath it.

Is this safe for everyone to try? Anyone with pelvic pain or a diagnosed pelvic floor disorder should get individual guidance before adding co-contraction work.
