Not to be anti-climatic about it, but as your holiday wallet thins, you may notice that seasonal celebrating causes your waistline to do the opposite. If something about all that food and spending makes you want to simplify and possibly even exercise, look to Gaiam, a green lifestyle website that offers yoga, exercise and meditation accoutrements (as well as $4.95 shipping pre-holiday shipping). We found this mini-trampoline. It comes with a DVD that promises you a low-impact cardio workout that will tighten your glutes and leg muscles. Could this be a way to jump for joy after the holidays?
