HIIT is a big buzz word in the fitness world right now. High Intensity Interval Training is defined as a workout that alternates between intense bursts of activity and fixed periods of less intense activity or complete rests. It is a great way to get your heart rate up and keep it up for a prolonged period of time, in turn this increases your metabolism and keeps it up allowing you to burn more calories than working at a steady state. It is a great way to exercise if you have limited time, you can accomplish quite a bit in 20-30 minutes. Many of us equate a good sweat to a good workout and this will get the job done. I have been encouraging the husband to use this type of training when attempting to run. Not only will it increase your aerobic capacity but it will help get over the mental block of attempting to go out for distance. For example, if you cannot run two miles straight I bet you can do it in an interval workout.
Give it a try, above is one I did on Monday. Pick a speed that challenges you, if you can run comfortably at 6.0mph try your run at 7.5mph. Choose your recovery speed at a comfortable walking pace. The recovery will allow you to bring your heart rate down enough to get ready to take it back up! It should be very challenging. I'd love to hear how it goes.
