Yes, you’ve got a bun in the oven. But that’s no reason to let the rest of you turn doughy.

Stay fit with pre- and postnatal exercise classes with master trainer Dara Zall Kelly, owner of Peapod Fitness.

Instruction before baby comes is tailored to your trimester and includes nutritional guidance. After delivery, the focus shifts to strengthening your core and building stamina through high-intensity cardio. Opt for one-on-one sessions, group classes with friends, or customized nutrition and fitness coaching via e-mail.

Kelly also makes home visits.

Which is just what you knead.
