“The J” offers group lessons in a 25-yard, competition-style swimming pool. Parent-and-infant classes ($10 for members, $15 for nonmembers) incorporate songs, games, and plenty of splashing for a fun introduction to water safety and exercise. Starting at age 3, kids learn to kick, paddle, and blow bubbles in group lessons. Kids can also join the Devil Rays team. Six group lessons start at $50 for members, $75 for non-members.
