I would like to use neutral grip pullups as my vertical pull on half body program. In the first 4 weeks it is prescribed as 4×6-8 (2-3RIR). My max pullups is BWx8 with strict form. It would not be possible for me to hit both RIR and target rep range, so should I ignore RIR just on this exercise? How should I progress? Should I prioritze moving up in reps or adding weight? Is there any pullups progression model you would suggest. Thanks for the reply.
