At Week 6 Day 2, failure. Not sure if it was the humidity, the crappy diet from the last couple of days, or not drinking a very large bottle of water throughout the day. I felt sluggish and my muscles didn’t feel like moving or trying that hard. Probably is due to the heat. I did the first 10 minute interval which was a challenge just to get there, I failed 4 minutes into the second interval, I walked for a bit but when I tried again I was only able to go a minute and than had to give up before attempting to tackle the hill. Sucks, I was doing so well.
