Too right. I definately echo what cavemancoder said. Awesome work. Your target may have been lofty as it was yout first challenge.
I didn't know That you were still doing shoulder, bi etc sessions. I would suggest cutting all that out and just doing the challenge. Give it your all and you'll now know tht you will reap the rewards.
I'm am just working on all the advanced work of Marks LHT programme. After completing that I intend to try something similar myself. I am surprised uou didn't notice more improvements avfridsy your chest and tris. Marks LHT sessions are doing great things.
