Sprint intervals are a type of workout that alternates between short bursts of intense running and periods of rest or slower-paced activity. For example, you might sprint for 30 seconds, then walk or jog for 1-2 minutes to recover. This method helps improve your speed, endurance, and overall fitness in a shorter amount of time compared to steady-state running. Incorporating sprint intervals into your routine can be beneficial for athletes and casual exercisers alike. You can do these intervals on a track, treadmill, or even outdoors. Many people find that using a timer or following a structured program, like those from fitness apps, can help keep them motivated and on track.
