You’ve been saying it since the beginning of the year: In 2015, you’re going to get into the best shape of your life. But, really following through on that requires changing up your routine — and we’re not just talking about setting a “wake up and work out” alarm one hour earlier. To help you crush your goal, R29 and SIX:02 are bringing you six seriously sweat-inducing, full-body-toning classes to try — all in one place and all for FREE (as long as you RSVP in time). As if that weren’t enough, there will be gratis salads and lemonades from Sweetgreen, DJs spinning tunes, a braiding station courtesy of Glamsquad, SIX:02 tank tops given to every participant, and the chance to shop loads of stylish workout gear. Ready to make a change? We thought so. First move: Click here to RSVP immediately. Second move: Get ready to party with us — endorphins guaranteed.
