Physical changes during pregnancy, such as weight gain, hormonal fluctuations, and alterations in posture, can impact exercise routines. As the body changes, pregnant individuals may find certain exercises challenging and require modifications. It's important to prioritize low-impact activities, such as walking and swimming, which can reduce strain on the body while maintaining fitness. Consulting healthcare professionals for personalized exercise recommendations is crucial to ensuring both safety and effectiveness, as appropriate modifications can facilitate a healthy pregnancy and physical activity engagement.
