Today's battle with HIIT

I came home from school today and did HIIT on the treadmill. The sprints (well, sprints for me for the first time in forever) were pretty rough. I made it through the 15 minutes but I was SMOKED. Despite how exhausted I was, I'm pretty proud that I made it and I'm looking forward to seeing my improvements. Alternating between weights and HIIT seems like a pretty good plan. I think I can do this.

Here's something awesome.
