Running Intervals
Search GoogleRunning intervals alternate controlled fast efforts with walking or easy-jog recoveries. Use the exact work, recovery, warm-up, and cooldown durations in the workout prescription rather than treating every interval as an all-out sprint.

Setup
- — Choose a clear, predictable route or treadmill and wear supportive running shoes.
- — Set an interval timer with the programmed work and recovery periods before starting.
- — Complete the programmed easy warm-up and build speed gradually before the first hard interval.
Execution
- — Run the hard interval at a fast pace you can repeat with tall posture, relaxed shoulders, and quiet foot strikes.
- — Walk or jog easily for the full recovery interval instead of stopping abruptly.
- — Repeat only while pace and technique remain controlled, then complete the programmed cooldown.
Breathing & coaching
- — Use steady, rhythmic breaths and avoid holding your breath during fast efforts.
- — Lengthen the exhale during recovery to bring breathing under control before the next interval.
- — The first fast effort should feel challenging but repeatable—not like a maximum sprint.
Progressions
- — Add one interval or slightly increase the hard-effort pace while form stays repeatable.
Regressions
- — Use shorter hard intervals, longer walking recoveries, or a brisk incline walk.
