I've been working out everyday since Jan 1st 2019 and I only workout about 10-15 minutes a day and it's really made a huge impact on my health and cardio/stamina. I just do pushups and sit ups, a little weight lifting and walking/jogging on a treadmill and that's it. Every single day.
Granted I have no job or any other responsibilities.
I started out not being able to do 5 pushups and now I can do a single set of 120-140.
Like it or leave it. Hey, where are you going?
