You often inject a little song and dance into your routine: weekday mornings (workin’ 9 to 5, what a way to make a livin’), while watching TV (today is where your book begins, the rest is still unwritten), and before a date (we don’t have to take our clothes off). To add in even more fancy footwork, sign up for Nia fitness classes at Be You Bi Yu. Nia (which stands for nonimpact aerobics) brings together the power of tae kwon do, the grace of tai chi, and yoga’s strengthening and balancing with the self-expression and lightheartedness of modern dance to get you moving and working underused muscles. Black-belt Lisa Geddings leads the 60-minute sessions, instructing you on how to do each step. You regulate the intensity of your workout, which feels more like a Saturday night out than a grueling exercise regimen (but by the end you’ll feel it). Sing it now: Everybody get on your feet, we know you can dance to the beat. Be You Bi Yu Wellness Center & Spa, 5602 Shields Drive, Bethesda (301-493-4911 or beyouspa.com).
