That thing has shaking all over the place. I don't think it's meant to go to an incline of 15, I doubt I'm meant to be climbing an incline of 15 for that matter.
I was a huffing and puffing machine during my 30 minute interval workout. I was that awkward girl who makes noises every so once in a while out of pity for herself.
If you're in need of a 30 minute workout that will most certainly make the most of your time, please write or print out the below workout and hop on the treadmill!

Sorry that chart is so tiny! Check out Julie's post at Peanut Butter Fingers for a larger version since that is where it's from :)
She said it was the hardest workout she's ever done on a treadmill, so naturally, I wanted to do it.
When I looked at the speed and noticed I would be walking and jogging up hill, I had my doubts. I know walking up hill is no joke, but this was seriously no joke.
Note: Don't hold on to the handle bars when it starts to get steep! That's cheating :)
What I loved most about this workout is how I felt like I might really die. My heart was pounding, I was losing my breath, and I really just wanted to omit those last two intervals! But I didn't, and I told myself, "You can do it!"
What I love even more than feeling like I'm going to die is realizing that you survived, and then you feel like you can do it all over again. Crazy, huh?
Question
Do you ever feel like you can't go on but once you do, you feel like you want to do it all over again?
No, maybe it's just me??
