Personally, I found myself getting injured easier and easier every year growing “older” (I’m still only on my 30s). Whether it was neck pains from working on the desk or leg injuries from falling on BMX or a mountain bike.
It’s been a year now I’ve been training multiple times a week in gym, sessions with PT, group trainings and solo, and kinda starting to enjoy it - looking forward for the next training session even if it’s just 2 days apart.
The way I see it wether you like it or not, to be a good dad you have responsibilities. You have to feed the family, mow the lawn, fix things around the house. But you have a choice, you can minimum standard that shit, nobody will really care and you save a bit of time. Or you can take that bit of extra care and time and give yourself the pride in a job well done.
Same goes with trying to look after yourself for the sake of not dying young for your families benefit if nothing else, doing jack shit is really easy and doing “enough” really isnt that hard its just way harder than jack shit. But going that extra mile for me, my ego, my pride and self image doesnt take that much longer or that much more effort.
