Rest as needed between sets. If set requires interruption, adjust as little as needed to complete next set uninterrupted. When scheme is listed as “5 x 5″, it always refers to “Sets” x “Reps”. Reminder: Position and range of motion- most specifically, a straight, strong lock-out- always govern weight.
Rest as needed between sets. Position considered, each set/ each arm is to be performed as heavy as possible- adjust weight between sets as needed. Same as above- position and range of motion always govern weight.
Rest any time during the set, switch arms each rep, and add a 2/1000 pause to any transition point that you are struggling with.
