A good treadmill workout should include a brief warmup, the actual workout, and a cooldown. Warmups typically last 5–10 minutes and are designed to gradually increase your heart rate and get blood flowing to your working muscles. You may want to start walking at a slow pace, then gradually build up to the pace you plan to use most during your workout routine. A typical treadmill workout depends on your goals. A few examples include: Steady state workouts (walking or jogging at a given speed and incline for 20–30 minutes), Interval workouts (alternating between a faster and slower speed every few minutes for 20–30 minutes), Hill workouts (alternating between a steeper incline and a lower incline every few minutes for 20–30 minutes). Regardless of your workout, you should always end with a 5-10 minute cooldown where you gradually decrease your intensity, incline, and speed, allowing your heart rate to return to normal. You may want to follow up your treadmill workout with stretching, foam rolling, or abdominal work.
