Welcome to the MamasteFit Blog! We’re excited to share with you a specially designed birth prep mobility flow. This flow is perfect for anyone in their pregnancy journey, but it’s particularly beneficial during the third trimester and even early labor. Our focus today will be on creating space in each of the pelvic levels, which is crucial for a smoother birthing process.

Understanding the Pelvic Levels

Pelvic Inlet (Top Level)
This area opens more with external hip rotation. Think of movements that involve knees moving out to the side. This creates space from side to side and is essential for allowing your baby to enter the pelvis.

Mid Pelvis
Once your baby engages in the inlet, they will navigate through the mid pelvis, which opens with asymmetrical movements. Shifting your weight from side to side while in open and closed hip positions will help create the necessary space in this critical area.

Pelvic Outlet (Bottom Level)
This is where your baby will make their final rotation during pushing. The pelvic outlet opens more with internal hip rotation, so bringing the knees in and the ankles out is key. It’s also important to allow the sacrum to move freely to relieve tension in the posterior pelvic floor.
Third Trimester Mobility Flow
In today’s workout, we’ll incorporate a series of hip mobility exercises targeting each pelvic level. Grab a yoga block and a bolster and let’s get started!
- Pigeon Pose: Begin seated with one ankle stacked on top of the opposite knee. Lean forward gently, breathing into your hip for about one minute on each side. This opens up the pelvic inlet, creating vital space for your baby.
- Half Lunge Position: Shift into a half lunge, rocking back and forth to open up the upper mid pelvis. You can use a block for support, allowing for deeper stretches. Do this for about one minute on each side.
- Adductor Rock Back: Straighten one leg out to the side and rock back into the hip. You can either hold this position for one minute or rock forward and back. This movement targets the upper mid pelvis and enhances inner thigh flexibility, facilitating your baby’s rotation.
- 90/90 Position Switches with Side Camel: Move into a 90/90 position and start by reaching towards the internally rotated leg. Extend in the hip and reach back for a hip flexor stretch, then place the hands behind you as you roll over the feet and switch sides. Continue for two minutes. These movements engage both internal and external hip rotation, critical for mid pelvis opening.




- All Fours Hip Shifted Pelvic Tilts: Place a yoga block under one knee and shift your weight into the elevated hip. Inhale to drop your belly toward the floor, exhale to round in the back, keeping your weight into the elevated hip. Keep shifting the hips for one minute, then switch to the other side. This helps create space in the lower mid pelvis, particularly important if your baby is having trouble rotating.
- Knees in Pelvic Tilts: Finish with pelvic tilts, bringing knees in and ankles out. As you did before, inhale to drop the belly to the floor and exhale to round in the back. Continue breathing through these pelvic tilts for one minute. This movement is essential for opening the pelvic outlet, making space for pushing during labor.
