We'll admit that most of us are too lazy to actually work out here. But we feel a little stronger when we walk down Degraw Street licking our ice cream cones just to see the chiseled people sweat and grunt through the open loading bay door at this hardcore gym. Take the free intro class to get the hang of it, and then dive into one of many affordable classes, from yoga to group lifting. Don't be discouraged by the skull and crossbones: what doesn't kill you will make you stronger.
