We’ve had a few people ask about the wedges our pregnant members use during class, so here’s a quick explanation.
These are pregnancy wedges. We typically introduce them from around 20 weeks onward for exercises that involve lying on your back.
During pregnancy, lying flat on your back for extended periods can sometimes place pressure on the inferior vena cava, a major vein that helps return blood to the heart. For some people, this may reduce blood flow and lead to symptoms like dizziness or light-headedness.
Using a wedge creates a slight incline, which can help improve comfort and support more optimal positioning during supine exercises.
So whenever we’re doing movements that involve lying flat for a while, we offer the wedges as an option to help members feel more comfortable and supported.
While the physiological effects of prolonged flat-back lying in pregnancy have been documented, there is limited high-quality research on long-term outcomes, so we take a cautious, comfort-first approach.
