Modified Planks
Safe core strengthening on hands and knees or incline to maintain abdominal strength without stress on belly.
📅 Safe Trimesters
⏱️ Recommended Frequency
5-8 holds of 10-15 seconds, 3 times per week
Overview
Modified planks allow you to safely strengthen your core muscles during pregnancy without the risks associated with traditional planks. As your belly grows, standard planks can put excessive pressure on the abdominal wall and pelvic floor.
Core strength is crucial during pregnancy for supporting your back, maintaining posture, and preparing for the physical demands of labor and recovery. Modified planks provide these benefits without putting your pregnancy at risk.
It's important to stop planks if you notice any doming or coning of your belly (the abdomen bulging outward), as this indicates too much stress on the linea alba (the connective tissue between abdominal muscles) and increases risk of diastasis recti.
