I have been recommended an exercise class by another new mum. Here is a link to the site: http://www.pregnancyandparenting.com...e_classes.html
classes are only $18 (when purchase 10 at a time). I've just booked in to start next week so I'll let you know how it goes. Classes are outdoors and if bubs are unsettled the instructor can show you ways of doing the exercise whilst settling bub.
