I really love my mom's group. It's Stroller Strides, and it's in Aliso Viejo, Laguna Niguel, Dana Point. It's not just exercise, but a wonderful playgroup for kids and an excellent support system for moms. You can go as little or as often as you like, so the kids really form great bonds with the other kids. It's been a routine for my son since he was 4 months old, and he's now 2.5. The moms are amazing! They have mom's night out once per month, and an activity once per week, in addition to the hour class and play-time after. Very "low-key"...Try www.strollerstrides.com for one in your area. Best of luck. Being around great moms is such a blessing!
