Swimming, like line dancing, combines graceful motion with strict physical discipline and should never be attempted until 30 minutes after eating. Practice safe strokes with today's Groupon: for $55, you get one week of half-day swim and activity camp at Swim Fanatics Swim Club in Greensboro (up to a $125 value). The weeklong, half-day swim camps run until Friday, August 5, with daily sessions held 9 a.m.–1 p.m.

The certified swimming coaches of Swim Fanatics Swim Club instruct wee waders ages 2–15 in proper swimming technique and water-safety basics, with a maximum of six swimmers per coach and one coach per four kids ages 2–9. Tadpoles will practice breathing and basic strokes as well as proper Marco Polo evasions and boogie-board Morse code. Each week has a theme, such as Purple People Eaters "Dino Discovery," which supplements its aquativity with nature-filled treks through park grounds as kids search for an elusive T. rex that frequently hides itself by donning Groucho glasses. Children also get a chance to escape the summer sun's stink eye with indoor group adventures and craft time. Parents should equip children's backpacks with plenty of sunscreen and a change of clothes for terrestrial activities. Camps are held rain or shine.
