I know you've had a heap of responses already, but regarding eating after you get home: Prep something in advance. Make dinner the night before, but double it. The next day after the gym just warm it up, eat, and relax. You'll spend ~10m extra the day before preparing extra and save yourself tons of energy and time the next day. It'll make working out seem a lot less daunting.

Try to fit a bunch of these in and eventually you'll have quite a lot more time. Prep food in advance, work out at home, you're saving well over an hour already.

I feel your pain regarding wanting to go part time so you have time for what you care about. I have many weeks where things pile up until the weekend, then it's all errands and chores all weekend. Such a drag.
