Learning to swim, like aging gracefully or enjoying dried fruit, requires acceptance of pruney fingers. Outfit your little ones for aqua play with today’s Groupon: for $79, you get one month of group swim classes (a $135 value) for children and adults plus annual registration fees (a $35 value) at SwimJim locations on 10th Avenue, East 66th Street, or East 96th Street (a $170 total value). Classes meet once a week. Those choosing to continue classes at regular prices don't need to pay additional registration fees for the first year.

SwimJim’s nautical instructors teach aquatic-adventure seekers of all ages with a systematic approach focused on confidence, spatial awareness, and muscular development. With a high teacher-to-student ratio and instructors trained in first aid and CPR, students learn in a safe indoor pool while receiving constant support and attention. Tots of 16 months–3 years gain early exposure to the water in a Swimbabies class, learning overall breath control, motor skills, and which pool noodles are safe to eat. Beginner Swimkids lessons teach students ages 3 and older submersion and basic paddling with the aid of a 4-to-1 instructor ratio, and advanced Swimjimmer classes mold more experienced amphibians in advanced stroke instruction.

Beginner, intermediate, and advanced level classes are also available for adults, helping grownups to become comfortable with the water, regain their old form, or travel to Hawaii without buying a plane ticket.
