Refresh my memory (I write so many programs, I don’t remember all of them): is the assistance exercise also done as a cluster? If so, dips aren’t ideal. BUT can be used if you use a bench or step to get into the starting position of each rep.
In the article the assistance lift is also a cluster. But we spoke when I ran this a few months back and you told me if I wanted to I could only do the main lift as a cluster and the assistance as regular sets 3 sets of 4 to 6 reps.
So that is the way I decided to do it is as regular sets as opposed to cluster
