The gym seems to clear out a bit this time of year and with good reason. Chicago only has a few months of killer weather to take advantage of, but that doesn't mean you should abandon your workouts for outdoor activities like drinking margaritas in the sun — at least not all of the time. In agreement? Equinox Fitness (multiple locations) and Chicago Sport and Social Club have come up with a way to enjoy the warm temps while retaining (or achieving) that bikini bod.

The two leaders in Chicago health and fitness will host a beach volleyball challenge every Thursday night through July 28 at North Avenue Beach (check out our countdown to Summer beach post!). Are you a punting pro? Prove it! Between the hours of 5 to 8:30 p.m., you can challenge the Equinox Beach Volleyball Team for a chance to win a one-month membership to one of four Chicago area Equinox clubs of your choice. Aside from a little practice, the only thing you need to do to compete is show up! Simply sign up at the Equinox Challenge volleyball court located on North Avenue Beach. Walkups are welcome, too.
