@Daydreamsinglorioustechnicolor Before living in Australia, we lived in Spain and Italy (and France of course and other countries) and I can guarantee you that the super sharp and healthy " nonnas" you see in Italy who ride their bike at age 90 to the daily markets, carry the shopping and look after their grand kids have never run a single jog in their whole life.
They eat very well, a colourful, varied and high in vegetable diet, are active, look after the garden and go everywhere on their bikes, when they are not sitting on their chair outside their home and looking at what is going on.
Doing an exercise you enjoy , love and makes you feel good will be relevant to your health. Not running if you hate every minute of it.
You are out of breath if you have to run after bus or kids. Doing some exercise that challenges you will be good and the science has proven that sharp and short burst off exercise give the same health benefits.
Use your kids for the HIIT sprints, give the phone to one and challenge the other to run against you.
and then look at something you have always wanted to try. Volleyball? Ballet? or even Krav Maga. You don't hav have the money for the gym membership but maybe you can ( and should ) find the budget for one activity that gives you pleasure.
Being active is important for health, alzeihmer's and cancer prevention. It doesn't have to be running. Walks at a pace fast enough to make it hard to have a conversation. And seriously look into podcasts or put a flyer in your neighbours letterbox suggesting to make a walking group at 6 am before school and work.
That way you combine the social to the workout which is as important for health.
