Week 1 - HIIT

Today was my cardio day so I decided to do a HIIT workout. Essentially, if you read any article online it will tell you that HIIT is a great way to burn the calories without muscle loss. Apparently, there is a longer fat burning effect. Or in other words, you will continue to burn calories even a few hours after completing the cardio workout.

All in all my workout was 31 minutes long. I started off with a 5 minute warm-up at 5mph. Right after, I shot it up to 9mph and jogged for a minute. It actually takes about 10 seconds to change speeds on the treadmill. I repeated this 6 times and did 10mph in the end. Here is my workout summary:

5 minute warmup at 5mph
9mph for 1 minute followed by 3.5mph for 3 minutes

9mph for 1 minute followed by 3.5mph for 3 minutes
9mph for 1 minute followed by 3.5mph for 3 minutes
9mph for 1 minute followed by 3.5mph for 3 minutes
10mph for 1 minute followed by 3.5mph for 3 minutes
10mph for 1 minute followed by 3.5mph for 5-10 minutes (cool down)
