Athlete's Club offers New Yorkers unparalleled access to gyms, restaurants, classes, and shops that focus on fitness and health. It's similar to Groupon, but the discounts never expire and you can reuse them to your heart's content. Chelsea Piers, Body Space Fitness, Clay, KettleBell Kitchen, Magic Mix Juicery, and Gustorganics are already onboard with Athlete's Club, as well as almost 50 other partners. The service not only helps local businesses thrive, but the deals are pretty sweet, too. Early members saw savings between $52 and $367, in just one month. With introductory memberships that start at $19 monthly and $129 annually, this might be the best decision you've made this year.
