One too many frosty margaritas by the pool this summer, ladies? Yeah, me too. But not to worry, Exhale Spa’s got your back. Tighten and tone in any of the spa’s Core Fusion or Core Energy Flow classes for just $10 a pop every Friday. Those who prefer pilates-esque exercise, go with the former. Yogis, try the latter. Both will reap the benefits of a firmer, fitter physique. Or at least burn enough calories to neutralize Saturday’s vices.
