Hey guys, I've been doing the 531 beginner template and loving it! The extra volume is really helping with my strength gains. I've been doing a variety of assistance exercises like chin ups, DB rows, DB bench, farmer's walks, etc. But I would like to also do both dips and back raises as well. The thing is, i only have the budget and space for either a Roman chair or a dip station. I just wanted to get some opinions on what the more beneficial exercise is long term? If you could only choose between one, which would you go with? Thanks!
