Getting to the gym is a kind of universal New Year's resolution, but if there was ever a year to forego a $100/month membership, it's this one. So Equinox is coming to you, assuming that in the midst of all this you're still hanging out at Saks. This weekend, the fancy gym is sticking masseuses and personal trainers on the sales floor, handing out over 20,000 guest passes in goodie bags and e-mailing their current members a 15% discount code for Saks. If you're a SaksFirst customer (which we're not so we can't tell you what it means other than spending a lot of money), Equinox will waive their hefty initiation fee and give you free Pilates class. And if you're super into this idea, there will be yogis striking poses in the 5th Ave. Saks windows for four hours this weekend, so grab your Stella for Adidas gear and head uptown. We, on the other hand, would rather cozy up with hot chocolate and POP's 'last' issue. But, to each her own.
