Some weighted behind the neck pull ups (+10kg). I prefer this one since you don't see a lot of people doing this at the gym. I usually get up to +15kg, doing 3 sets of 5-8 reps. Also incorporating some dropsets after your working sets works hella fine too, after getting rid of the weight your pull ups will fly up.
I have something important to announce in my next video. It will be the last episode.. so stay tuned.. #asianpowerbuilders
