TL;DR

Sprinting improves mental performance and physical well being.

Steady-state cardio is not nearly as impactful, because it’s too easy and there’s no distinct contrast compared to talking.

Personal experience

Every time I do a hard sprint session, I have such great mental focus, clarity, and creativity.

Sprinting “wakes me up” from my ordinary routine, and helps truly activate my brain to a higher potential.

It simply works, and for that reason, sprinting sessions are now a vital requirement in my habits.
