Ready to drag your post-pregnancy body to the gym — but at the crucial moment, the baby needs you? Consider popping the kid into a car seat and heading to Move You Fitness Studio in Essex, where you can sweat together as a family in classes such as Mommy & Me Movin.' Class times range from 5:15 a.m. to early evening, so you're likely to find something that fits your schedule. The fees are family friendly, too; most classes have a drop-in rate as low $5 per class. The studio also sells six- or 12-class punch cards, so you don't have to commit to a yearlong membership to participate. Still stuck on the couch? Take part in a free playgroup during which kids and moms can play, chat, snack, and stretch with mats and balls. Or leave the little ones at home and enjoy a Mom's Night Out party that includes an hour of line dancing or Zumba followed by adult snacks and drinks.
