In addition to physical benefits, exercise inspires a brief endorphin rush on par with staring down a grizzly bear or jumping a dirt bike over Evel Knievel. Keep minds and bodies alert with today's Groupon: for $17, you get a one-month single membership (a $34.95 value) along with a Global Access card (a $20 value) at Snap Fitness (a $54.95 total value).

Snap Fitness's around-the-clock gyms enable members to work on their physical wellbeing with a cornucopia of fitness equipment. With 24-hour access, members don't have to let The Man or a random street man tell them when to help themselves to Snap's strength equipment or top-of-the-line cardio equipment, which features televisions and other media diversions. Even if you exercise during conventional hours, Snap's friendly, unintimidating atmosphere will provide a refreshing change of pace from any meat-market gym or tough elementary-schoolyard workout. Members also enjoy nationwide access to all Snap Fitness locations, ideal for working out while traveling. Groupon customers who choose to continue their membership with Snap Fitness during the one-month Groupon period can do so without paying the standard $50 enrollment fee.
