LOL yeah suga I thought you might struggle a bit with the pull ups. But thats fine. You know what your goal is here!
I think on your old workout plan you were getting stale with it. Your bod was like " hey this is old and sucks" Just sucks because you had been doing it for so long.
On your work sets, do them all at the same weight. If that weight seems too easy just note it in your log and then increase accordingly next time. But dont make your increases too big at any one time cuz we want to carry this on for 12-14 weeks, adding weight every 2nd or 3rd workout. Thats why I dont want for you to change your work set weight. Its gonna make you feel good to see yourself progress this way and believe it or not it also help keep you fresh. After you see where you need to be on your work set weight your should only be adding 5 lbs at a time for your increases.
