I miss my old body but I've never been happier
Not gonna lie, becoming a dad destroyed my metabolism. I was ripped before kids, now I've got a dad bod for sure. Used to spend 2 hours at the gym every day. These days I'm lucky if I get to the gym once a week and it's usually just 30 minutes. I look at old photos and I'm like who is that guy? But here's the thing, that guy was pretty miserable and vain. Now I've got energy for my kids and I don't care as much about how I look. Trade off seems fair.
Two kids in different schools means I'm too busy with logistics to worry about my old gym routine anyway. Honestly the dad bod comes with the territory and sounds like you're cool with that trade off, which is what matters.
