The center of gravity in a pregnant body moves forward by roughly 2 to 3 cm each trimester. That sounds small until it's your body trying to fold forward over a belly that wasn't there last week. Almost every standing pose, every seated forward bend, every supine opener needs a different floor than it did before — and the only honest way to raise the floor is with something that doesn't compress under load. A wooden block does this. A foam block does not.
Eugene's wife practiced through both her pregnancies in 2019 and 2022 with the same set of three ash blocks Roman made for her. The blocks went under hips, between knees, behind the back, and once under the head for an entire third trimester of side-lying rest. They're still in the house. This guide is built from what she actually used and what she stopped using around week 28.
We'll cover six poses by trimester, the two heights that matter most, and the one pose every guide recommends that we'd suggest you skip. The skip matters more than the rest.
Why Prenatal Yoga Needs Props
Pregnancy creates unique physical challenges that make yoga blocks not just helpful, but essential for safe practice.
Physical Changes Requiring Support
- Growing belly - Expanding abdomen affects balance and range of motion
- Shifting center of gravity - Balance becomes increasingly challenging
- Joint loosening - Relaxin hormone makes joints unstable
- Breast enlargement - Changes upper body weight distribution
- Postural changes - Forward head and rounded shoulders from breast weight
- Pelvic floor pressure - Growing baby puts pressure on pelvic organs
- Lower back strain - Increased lumbar curve from belly weight
How Yoga Blocks Address Pregnancy Challenges
Blocks provide essential support for safe prenatal practice:
- Stability enhancement - Prevent falls and loss of balance
- Comfort improvement - Make poses accessible despite body changes
- Proper alignment - Maintain healthy posture during practice
- Injury prevention - Reduce risk of overstretching loose joints
- Energy conservation - Allow rest and support when needed
- Confidence building - Provide security for continued practice

Frequently asked questions
Are wooden yoga blocks safe during pregnancy?
Yes, wooden blocks are often preferred during pregnancy because they do not compress under a shifting centre of gravity. Foam sinks unpredictably as the body's weight distribution changes each trimester. Eugene's wife practiced through both her 2019 and 2022 pregnancies with the same three ash blocks Roman made at the Kostopil workshop. Always consult a qualified prenatal instructor for pose selection. See /products/wooden-yoga-brick.
Where do I place a block under the hips during pregnancy?
At the medium height (15 cm) under the sit bones for seated poses, tilting the pelvis slightly forward so the belly has room. As the belly grows through the second and third trimester, the block often shifts to the tall side (23 cm). Eugene's wife used all three heights across her second pregnancy in 2022. Order a pair from /collections/yoga-products for hip support work.
Can I use blocks for side-lying rest late in pregnancy?
Yes. One block under the head and one between the knees keeps the spine neutral in side-lying rest during the third trimester. Eugene's wife used a block under her head for her entire third-trimester side-lying rest in 2022. The wooden block does not warm or shift like a folded blanket. Ask Alex about custom softer-edge blocks for pregnancy at metadeskukraine@gmail.com.
Do I need to buy new blocks after pregnancy?
No, the same blocks work for post-partum recovery and general practice. The three ash blocks Roman made for Eugene's wife in 2019 are still in the family home, having supported two pregnancies and years of general practice since. This is one of the durability advantages of wood over foam. See long-term care instructions at /products/wooden-yoga-brick or start with a set.
Can I get a custom prenatal block set?
Yes. Alex offers a three-block prenatal set at metadeskukraine@gmail.com sized to match the practitioner's height, with softer 8 mm edge rounding for comfort against the belly. Roman cuts these individually at the Kostopil workshop with a 2 to 4 week lead time. Include your due date so Alex can prioritise shipping. Standard blocks work too and ship faster from /products/wooden-yoga-brick.
