Why run/walk intervals work

Alternating running with walking lets you practice good form, keep your effort controlled, and build total workout time without turning every session into a suffer-fest. Good pacing trick: finish feeling like you could do one more repeat.

Good pacing notes

Run intervals should feel steady, not like an all-out sprint. If you cannot talk in short phrases, shorten the run interval or lengthen the walk recovery.
