This is based on the prenatal aquafit class only. The class is amazing and I highly recommend it, but this is only a 4 star review because I can't speak to any of the other classes or facilities at the JCC.
I love that the pool is salt water instead of chlorine. When I was pregnant I really wasn't comfortable with swimming regularly in a chlorinated pool. The class is tough but it feels so good to be weightless and buoyant when you are pregnant.
The locker area is clean, nothing fancy. Bring your own lock.
