While swimming or doing water aerobics, some pregnant women desire using some of the varied exercise aids. These can include water weights, flotation devices, and so forth.
You might consider using them to help you exercise or to help you relax. Many moms resort to using flotation devices in the final months of pregnancy. This allows more of your body to remain underwater, while allowing you to float, much like your baby floats.
Kick boards are another water aid that can be useful while pregnant. Try taking a kick board with you as you semi-float around the pool. It can be useful to lie your head on as you float, or you can use it to hang on to while kicking your legs away.
A deep-water flotation belt can be handy if you aren't the best swimmer or you are trying to do your workouts in the deep end. The problem is that by the end of the second trimester, the belt may not fit your growing abdomen. Exercise caution when in deep water and talk to the lifeguards and other pool personnel about the use of flotation belts.
