If you are struggling with pull ups. Utilize the PLP system written this past month. It will help on other factors such as thickening your back, chest, defining legs some and helping your waist.
Since from your conversation i assume you cannot do 10 consecutive pull ups you would start at 1. do 1 pull up 1 push up and 1 lunge on each leg, add a rep every day, do the program for 60 consecutive days. It will help you bring up your pull ups and others along the way.
Its a neat accessory program to be done 4-6 hours before or after your actual lift. and should help with your lack of being able to touch the bar.
