I generally go as soon as I can after the creche hours open at my gym (8:20am). Or if it is a kindy day I go straight after kindy drop off (generally get there about 8:40am).

If I have something on in the morning which means I can't get to the gym I will go before all the children wake up (gym opens at 5:25am and I am generally back home by 6am as I do a quick work out).

I aim for 3 times per week, but often settle for 2 times. And while I do like classes, I will more often do cardio and then the strength training weights line (set of 6 exercises). Classes are harder to coordinate with sleep/feeds/arriving on time etc.

None of this really helps you PN as I don't work and I live super close to my gym.
