Here's a more straightforward hack that worked wonders for me:
you simply run every single day - no excuses* - but only for 10 minutes. You may absolutely run longer if you wish, but the minimum quota is 10 minutes. It's simple: everyone can do 10 minutes, regardless of your current shape. Everyone _has_ 10 minutes, even Jeff Bezos. No excuses: 10 min every day.
After 2 years of doing this, I am the healthiest and happiest I have ever been. :)
No real source on this, but I assume that this is some sort of 80/20 thing, where a 10-15 min run will yield about 80% of the health benefits of a 1h run.
*except when you suffer from any type of viral infection - don't run with a viral infection.
