Pregnancy can make your own body feel unfamiliar — heavy, achy, hard to carry. Swimming changes that. In water, you are weightless for the first time in months: hips relieved, spine lengthened, breath easier. This calm, practical guide takes you from your first cautious swim to your final weeks, and beyond. It shows you how to get your midwife's or doctor's go-ahead, choose safe water, ease into the pool without slipping, and build a gentle, joyful session — the weightless hour — you can actually fit into your week. You will learn which strokes suit each trimester, how to protect your pelvic floor and core, how to ease back pain and swollen legs, and how to stay safe in open water. Every chapter includes the red flags that mean it is time to stop swimming and call your care team. No pressure, no guilt, no complicated kit: just the support of water, exactly when you need it most. Part of The Pregnancy Companion Library.
