Program is actually pretty simple but it works great for both newbies and advanced trainees.
Do 10 sets of wide grip pull ups doing 50% of your rep max in each set, with 1 minute rest between sets.
Eventually try to add reps whenever possible- progressive overload is crucial for fast muscle gains.
Train 3 times per week with 48 hours rest between workouts. As time goes by and your recovery ability will increase you can start doing that program 4 or 5 times per week
