Like a tree house, a gym never lets non-members inside and always deflects frogs fired from the neighborhood bully’s slingshot. Hurry up the rope ladder with today's Groupon, good for a one-month membership to the Trotter Family YMCA. Choose between three membership options:

• For $29, you get a one-month individual membership, good for one adult (a $60 value).
• For $22, you get a one-month senior membership, good for one adult
• For $39, you get a one-month family membership, good for two adults and two children (an $85 value)

All membership levels receive full membership benefits, including free child care, free parking, free towels, and no contracts.

The Trotter Family YMCA keeps clans hale and hearty with 8,000 square feet of strength and cardio equipment, batting cages, a women's-only center, a healthy-minded restaurant, and a heated outdoor pool open year-round. After a certified trainer gauges your vigor, dexterity, and charisma with a free comprehensive wellness orientation and polar body age assessment, you'll have free rein of the Y's muscle factory, as well as its various fields and courts for basketball, tennis, soccer, and racquetball. Group-gravitators, meanwhile, can sample a more exotic flavor of exercise during any of 140 weekly group exercise classes such as Zumba, body combat, and bhangra dancing. The YMCA also supplements sweat donations with nutritional seminars. Guest passes make it easy to invite along a heart-healthy sweetheart, or at least a more reliable weight spotter than your easily distracted genie.
