Interval Running Guide: Build Power and Endurance

Master interval training with our expert guide. Learn correct form, avoid common mistakes, and improve your cardiovascular strength with structured sprints.

How to Perform

  1. Begin with a five-minute light jog to increase blood flow and prepare your joints for higher intensity.
  2. Accelerate to a sprint speed that represents roughly 80 to 90 percent of your maximum effort for the specified duration.
  3. Maintain a tall posture with eyes forward and drive your knees upward while pumping your arms in sync with your stride.
  4. Transition immediately into a recovery period consisting of a slow walk or complete rest to allow your heart rate to drop.
  5. Repeat the alternating cycle of high-intensity work and low-intensity recovery for the desired number of rounds.
  6. Finish the session with a five-minute cool-down walk to prevent blood pooling and facilitate recovery.

Common Mistakes

  • Shortening the recovery periods before the heart rate has sufficiently stabilized.
  • Heel striking heavily which increases impact stress on the knees and ankles.
  • Leaning too far forward or arching the back excessively during the sprint phase.
  • Starting at a maximum sprint speed that cannot be maintained for the full interval.
