If you are looking to lose weight, here is a scientifically proven way to rev up your natural fat loss machine and lose more body fat than you have ever done with high intense interval training for cardio...
And the best part is that it only requires 10-15 minutes in the morning and you can get 3-9x the results of normal cardio! The fastest way to burn fat is to work out in the morning, most people are aware of that already.
 They walk or jog for 30-40 minutes in the morning, but they are wasting their time doing long boring cardio when the faster, scientifically proven method is high intense interval training (HIIT) for just a few minutes before breakfast.
If you have what it takes to wake up 20 minutes earlier, put on a pair of shoes, a pair of shorts and a t-shirt you can do this and keep in shape, guaranteed...
Find a treadmill or run outside...
Go hard for 1 minute by running at a high speed to get your heart rate up...
 You can do sprints, but it's suggested to run at a 70-90% intensity level of your maximum.
Cool down by walking for 1 minute after having done your 1 minute of running.
 This is to cool down and slow down your body significantly, and to get your heart working towards getting back to rest...
After 60 seconds go right back and start running for an intense 60 seconds again...
And repeat this for 5-10 sprints.
You will now have worked out for 10-20 minutes and you have put your body in fat burning mode by not having eaten before your workout, and by getting the most benefit out of your workout by doing HIIT.
This workout can be so effective that you may need to alternate between something lighter than running and walking, but as you get better you want to alternate between sprinting and jogging for 20 minutes (10 sprints)...
 That is your goal.
