are you up for a challenge?

So, I was wanting to come up with a challenge for September & hoping some of you would like to tag along. I was thinking along the lines of a squat challenge, since one of my goals is to work on that back side. Of course, the first of September came & I still hadn't put it together. I found this one from Tribe Sports today & thought it was a great one!

So what do you think? Are you up for the challenge?  I plan on making up my first 2 missed days today, along with the day 3 workout. Join in any time!
