Holy cow! I've been beaten. Week 4 is incredible. Two five minute and two 3 minute jogging sessions? With minimal walking in between? Are they trying to kill me? LOL
It's gotten progressively harder (and I expected it to) but it seems like it was such a big jump from last week. I barely made it through and thought I might have to be scraped up off of the gym floor!
OK...that's enough. I don't want to scare anyone off!!
