I find it easier to exercise every day than to exercise 2-3 times per week.
Working out every day makes it a non-negotiable. Zero energy is spent deciding—the habit already made the decision.
But when I exercise only a few times per week, it’s easier to convince myself I’ll do it tomorrow. I end up spending far more energy planning when to fit in a workout than if I just spent that time working out first thing every morning.
If we don’t need to negotiate with ourselves, the path is easier to follow.
