Getting back in shape after becoming a dad destroyed my self image
I used to be fit, played hockey, felt good about myself. Then the kids came and suddenly I had zero time, was exhausted all the time, gained 40 lbs and didn't even notice until I saw a photo. Spent 2 years just feeling bad about how I looked. This past year I made it a priority to get back to the gym even if it was just 4am before the kids woke up. Lost 35 lbs, back to playing in a beer league with guys from work. It's not about vanity anymore, it's about feeling like myself again. My kids see me taking care of myself and I think that matters too. The mental health part has been bigger than the physical part honestly.
Early mornings before the kids wake up changed everything for me. I know it sounds brutal but even 30 minutes at 5:30am gives me back some of that self image. Plus the mental clarity helps with the parenting side of things.
Don't discount the wins that come with being a dad though. Different kind of fulfillment but it's real. You'll get some of that athletic energy back eventually when you have more bandwidth.
