A word from your friends at Social Workout, who believe in taking care of both home and body. We've been quiet in this space of late, though we have written a few items of interest for A.T. loyalists -- like about how fitness and staircases are all the rage among the Renzo Piano set, and how barefoot running is all about de-cluttering, and, weirdly, has a lot in common with D.I.Y., not to mention Raw Food. But we're prompted to interrupt your regularly scheduled programming now just to pass along a single important message: This Sunday is the Summer Solstice, and we will kick off our unusual Feats of Summer Challenge. The Challenge will run through Labor Day, and is engineered to induce feelings of extreme wellness. Should you be looking for a mind-body push, please join us.
