I did this Treadmill workout and man o man was my heart in my throat well before it was done.
This is no joke high-interval work out and will get your blood pumpin'
This is not a beginners workout.
I don't care if you've been running for ages,
if you are not used to interval training
--I am--
this will kick your bottom.
HOWEVER, do not be discouraged if you are a beginner.
Give it a go by cutting the time time in half...instead of 45 min try it for 22. It is repetitious.
Now get up and give it a go!
You'll feel ALIVE afterward.
Trust me.
