No problem! This quick treadmill run will burn a ton of calories in just a little bit of time. #treadmill #workout #burncalories”]
*Calories burned are based on running at the following levels, at a 3.0 incline:
30 second sprint – 10.0 mph
1 minute sprint – 9.0 mph
2 minute sprint – 8.0 mph
4 minute sprint – 7.0 mph
Be sure to modify and work at your own level. If you liked this workout, try this great treadmill workout. And as always, for best results make sure you are eating The Happy Gal Way. Click HERE to check out my new cookbook.

  1. 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

    1. Thanks for your comment. This is a great reminder to always work to your own level. I’m sure this will help a lot of viewers.

    2. Hey there, when I did this work out the treadmill only indicated that I burned around 250 calories. Is it just not calculating the fact that they are intervals and your heart works harder and your body burns more with this type of training? Thanks!

      1. Thanks for your question Michelle. My treadmill indicates that I hit the 400 calorie mark when I follow the speed intervals listed – 30 seconds at 10.0, 1 minutes at 9.0, etc. Of course, that doesn’t take into account EPOC (Exercise Post Oxygen Consumption) that continues to burn calories for up to 24 hours after your workout. Because it’s imperative that you run at speeds that are safe for you, you might need to slow down the speed, and therefore your treadmill might not register that you’ve burned 400 calories during your workout. But due to the high intensity intervals, you will continue to burn calories throughout the day. Hope that helps! And good for you for doing the workout! It’s a tough one, but it feels so good!

  2. So I’m new to treadmill is the speed the incline as well? If you can email me that would be great
