Tried today to focus on just swings and sumos. Holy hell. This 35 is a new game. In 16 minutes after 60 sumos and 120 swings I felt like a pack a day smoker who had to run from a dog. I had no air capacity. I felt pretty good using the 20 and I will not go back to it out of pride. Faith No More did an excellent job of keeping pace. Tomorrow we do it again as it seems whatever I ate has done its damage and I have minimal heartburn and stomach issues. Becoming a man is tough, comrade.
