    I love doing intervals on the treadmill but the suggested speeds here are unrealistic for most people. While the time is short, the speed is so fast that most people could not do it. I recommend slightly slower speeds and a longer interval to achieve the desired calorie burn. Yes it will take more time but at least the risk of injury is lower. Maybe it’s just because of my height 5’3″ that I am unable to achieve these speeds but this is what works for me.

    30 second sprint – 8.0 mph
    1 minute sprint – 7.0 mph
    2 minute sprint – 6.5 mph
    4 minute sprint – 6.0 mph
