We need a gym.  The construction workers on Scuttle Hole Rd think we are crazy because we have been biking and running trotting past them each day in weather that would melt even the thickest of skins. I like Exhale in the city, and the one in Bridgehampton looks promising-as a spa that is, unfortunately their physique 57 classes are not going to cut it.  We want to sweat...we just want to do it in a comfortable 70° environment. Let us know your favorite gyms out here so we don't wither away before the summer's over.
