I tried this high intensity interval training (HIIT) workout on the treadmill last Friday and was sweating buckets when I was finished. It was so effective and since the speed, intervals and incline kept changing it kept my body guessing the entire workout. HIIT is the best way to get a high fat burning workout in that will really challenge your body in the least amount of time.
Make sure you properly warm up and cool down to get the best results. Listen to your body -- if it doesn't feel right don't push yourself! Scale the speed or incline down a bit if you need to and work your way up.
What did you think of this workout? Do you have any other HIIT workouts you love?
