Thanks for the help guys.
I have done my second full week last week, check my logs for more details (went snow boarding in between) this was at level 1.
I completed day one with 27 reps and I was quite surprised that the three times I have done day one I have improved each time. I am doing 3 body rows for each pull-up this is done using a towel over my Powerbar door pull up machine thing, with my feet about foot the other side of the door this allows me to keep the angle more horizontal but still pull myself to my chest (I watched the cross-fit body row tips videos to make sure I was doing the best version I could with my set up).
I managed with body rows to do D3 in 4 mins. I was going to level up and do level 2 today but I after reading the last post on here
I am not sure whether to stick with L1 until I can do a 'Proper' pull up or if the increased level will help me lose weight and get stronger to do the pull up quicker. What is your advice what did you do did it work?
