While Pilates is generally pretty bump-friendly, there are certain exercises and moves you should avoid when pregnant. Our experts all agree that in general, laying flat on your belly or back (which can restrict blood flow) should be avoided after the first trimester, along with high-impact and contact sports and anything that causes pain or discomfort. If we're talking Pilates specifically, Di Lanzo recommends steering clear of "deep twisting movements, intense abdominal exercises like crunches, and any high-impact activities that involve jumping or rapid direction changes. Exercises that involve heavy lifting or putting pressure on the abdomen should also be avoided." She recommends attending a class (like the BabyBarre class at Paola's Body Barre) with a pre-natal trained instructor who can guide you through the movements for optimal results and peace of mind. When it comes to knowing your limits, ultimately, "every body is different", highlights Tiwari, "you’ll know better than anyone else whether you should back out of an exercise or whether you can push yourself a bit further."
