As far as fitness goes, it’s always much easier when you’re doing something you love. That’s why the Cardio Dance class at CLAY in Union Square is the perfect way to mix up your weekly routine. The one-hour class is a work-out, but perfecting your dance moves after doing 30 minutes of in-class cardio to the beat is the best antidote to a long day at the office. Dancing isn’t your thing? Maybe try TRED, a treadmill interval training class that puts spinning to shame. Or Abs Blast, described on the Website as an “intense and direct hit to the abdominal region.” Whatever your pleasure (or weakness), CLAY’s zen-like space has options for all.
