1 hr is 4% of 24 hours, but you sleep for 8 of those. So it’s actually 6.25% of your waking hours. And assuming you have to work an 8 hour day, it’s 12.5% of your non-working waking hours. I say this as someone that goes to the gym almost everyday… you have to actively prioritize it over other important things competing for your time. It’s not “jUsT 4% of yOuR day!1!” Don’t make it sound so easy.
