Anything cardio for me, we've just bought a treadmill which will hopefully help, there's no chance of me getting to the gym in the next few months !!
Ooh and I'm trying to do a few toning reps on legs, arms & tum after each feed. If I only do 2 sets of 12 after each feed, over the course of 6 feeds, it'll add up to quite a nice workout.
